Great grandfather, Jurian Haff, was a 1640s Field Trumpeter in the Army of the Dutch Empire of Brazil

 

Jurian (Juriaen/George) Haff’s Military Service: Full Exploration

All known details trace back to a single primary document: the Brooklyn Dutch Reformed Church records (dated 22 November 1662, under “Orphans of the Deaconry”). This entry was created when Laurens Haff (age ~13) and his half-sibling became wards after Teuntje’s death. It explicitly lists Jurian’s origin, rank, unit, commander, posting, and exact discharge to establish the boy’s legitimacy and guardianship. No WIC muster rolls, payrolls, or personal military files naming him have surfaced in public archives or digitized sources.

Verbatim Primary Record Quote (from the 1662 Brooklyn Church entry)

“LAURENS HAFF from Brazil, aged about thirteen years, was the son of ‘the late GEORGE HAFF from Auspurg (Augsburg), Foot Trumpeter of the States of the United Netherlands under Captain Claassen, who duly discharged the former on June 23, 1649, and of TEUNTIE STRAETSMANS (STRAETSMAN) from Culenburg…’”

The same church records (and later genealogies quoting them) add that he served “under Count John Maurice of Nassau-Siegen, Governor-General of the Dutch Empire of Brazil, at Fort Antonio at the mouth of the river Parahyba de Norte, which was changed to the name of Fort Marguerite in honor of the sister of Count Maurice.” He was “honorably discharged from service on June 23, 1649, in Brazil.” 

Service Profile

• Rank: Foot / Field Trumpeter (Dutch: trompetter). In 17th-century armies this was a skilled specialist role—responsible for signaling commands, charges, retreats, parleys, and ceremonies across noisy battlefields or garrisons. WIC soldiers often included German Protestants like Jurian (from Augsburg, Swabia).
• Employer / Unit: Dutch West India Company (WIC) / States of the United Netherlands, under Captain Claassen (Claussen).
• Commander & Governor: Served during / under Count Johan Maurits van Nassau-Siegen (governor-general of Dutch Brazil 1637–1644; the fort renaming honors his sister).
• Posting: Fort Antonio (renamed Fort Marguerite), mouth of the Paraíba do Norte River (modern João Pessoa area, Paraíba state, Brazil—near Recife/Pernambuco). This was a key defensive river-mouth fort guarding Dutch-held northeast Brazil. 
• Service Period: At least 1637–23 June 1649 (tied to Count Maurice’s arrival; discharge came during the late phase of Dutch control). His twin sons Laurens and Pieter were baptized 30 June 1649 in the Recife Dutch Reformed Church (Fort Marguerite vicinity), so he was alive and in Brazil at discharge. 
• Outcome: Honorably discharged in Brazil. He died shortly afterward (1649–1654). Teuntje and Laurens joined the ~1654 Dutch refugee exodus after the Portuguese reconquest.

No specific battles, wounds, promotions, or pay details are recorded—typical for a non-officer WIC soldier. He was likely a career garrison trumpeter rather than a campaign hero.

Historical Context (Dutch Brazil / New Holland, 1630–1654)

The WIC seized northeast Brazil from Portugal in the 1630s. Recife became the capital (renamed Mauritsstad). Forts like Antônio/Marguerite protected river access and sugar plantations. Count Maurits’s governorship (1637–1644) was the high point—arts, science, and tolerance flourished alongside military defense. By 1645–1654 Portuguese forces (aided by locals) gradually reconquered everything; 1649 fell in the brutal endgame. Thousands of Dutch, Germans, and mixed families fled in 1654 under capitulation terms—exactly when Teuntje and Laurens reached New Amsterdam. 

Sources & Cross-References

• Brooklyn Dutch Reformed Church Records (Holland Society Archives, pp. 223–227 etc.) — the 1662 orphan entry is the foundational document. 
• Quoted in: Genealogy of Delbert James Haff (full text), Centennial History of Missouri (p. 423), Allaben’s The Crall Ancestry, Teunis G. Bergen’s Early Settlers of Kings County, Riker’s History of Harlem, Brouwer Genealogy Database, WikiTree (Haff-43), Geni profiles, and modern articles (e.g., Gotham Center on Teuntje Straetmans). 
• No contradictions across sources; all derive from the same church record.

This fleshes out the brief “field trumpeter… under Captain Claassen… Fort Antonio/Fort Marguerite… discharged 23 June 1649” from our Missouri book excerpt into the complete picture. The service placed him (and later his widow/son) squarely in one of the most dramatic colonial chapters of the 17th century.

Consolidated Notes & Primary Sources

The core military and migration story comes verbatim from the Centennial History of Missouri (Walter Barlow Stevens, p. 423) and the 22 November 1662 Brooklyn Dutch Reformed Church “Orphans of the Deaconry” entry (Holland Society Archives). These records are the single primary source for Jurian’s origin, rank, unit, commander, fort, and discharge date.  

All Recife baptisms, Teuntje’s remarriages, Laurens’ apprenticeship, and the 11 children are drawn from compiled Dutch Reformed Church registers (Recife, New Amsterdam, Flatbush, Brooklyn) as summarized in:  

• Teunis G. Bergen, Early Settlers of Kings County  
• Brouwer Genealogy Database  
• WikiTree (Haff-43)  
• Gotham Center articles on Teuntje Straetmans  
• Long Island genealogy family sheets

No original WIC muster rolls naming Jurian have been located; the 1662 church entry remains the authoritative document. The 1654 Brazilian exodus (Portuguese reconquest) explains the family’s arrival in New Netherland exactly when New Amsterdam was still Dutch.

This revised summary corrects the birthplace of Teuntje, adds her full marital/children history, includes Laurens’ twin brother and 10 additional siblings, tightens Jurian’s death range, and integrates the military details without altering our direct blood line. The downstream generations from Margarietje onward remain exactly as you provided and are strengthened by the DNA match reference.

Captain Claes Hendrickszen Lock: Prominent 17th-century sloop owner in the Dutch colony of New Amsterdam

Claes Hendrickszen Lock, our 9th great-grandfather, (also spelled Claes Lock or Claes Hendricksen Lock) was a Dutch immigrant, sloop captain, merchant, and civic/military participant in New Netherland (later New York) during the mid-to-late 17th century. 

Biographical Details

• Birth and Origins: Circa 1646–1649 in Amsterdam, Netherlands (listed as “jm van Amsterdam” [young man from Amsterdam] in his marriage record). His parents are unknown in surviving documents.
• Death: Before 5 April 1692 in New York (his wife is called “last widow of Claas Kock [Lock]” in her father’s will that date). 
• Spouse: Kniertje (or Cuiertje/Cniertie) Hendricks (baptized 24 October 1649; died after 1728), daughter of Hendrick Willemsen (a baker in New Amsterdam) and Femmetje Joosten. She was the widow of Walraven Claerhout (married 1668; he drowned 21 June 1670 while aboard one of Lock’s sloops). They married 18 October 1671 in the Reformed Dutch Church, New York.
• Children (all baptized in the New York Reformed Dutch Church; these match what Gemini listed):  
• Femmetje (bapt. 20 Oct 1672) m. Dirck Andriessen  
• Catryntje (bapt. 2 June 1675) m. Jochem Verscheur  
• Margrietje (bapt. 20 Dec 1682) m. Joost Schomp  
• Hendrick (bapt. 16 May 1686; likely died young)  
• Adriaentje (bapt. 14 Nov 1688; likely died young)
• Kniertje had one earlier child (Belitje) from her first marriage. 

Maritime and Merchant Career

Lock was a leading sloop owner and trader on the Hudson River route between New York, Albany (Beverwijck/Fort Orange/Willemstadt), Esopus (Kingston), and the South River (Delaware). He first appears in Albany-area records around 1655–1662.  

• Vessels: Owned the Vergulde Hoorn (Gilded Horn; documented 1662, with skipper Arien Claessz), the Hester (1679), and the Sarah (master in 1684).  
• In 1674 he signed an agreement among sloop owners to regulate traffic and freight charges using a lottery-style pooling system based on vessel size/weight.  
• He frequently acted as arbitrator or examiner in trade disputes and appears in Albany court records for shipping lawsuits (1668–1673). 

Military and Notable Actions

• Second Esopus Indian War (1663): Served under Director-General Peter Stuyvesant; on 29 August 1663 he and Thomas Lodewyck Lewis were ordered to remain in the Esopus area until further instructions. 
• Rescue Mission (circa 1667): Contracted to travel to the New Haven Colony (Connecticut) to retrieve Albrechie (Albrechtje) Hendricks, a woman held captive by Native Americans since the 1655 uprising (she was a sister in a group of three Hendrickse sisters taken at Yonkers). This appears in Albany/Fort Orange records and his WikiTree sources. 

Civic Roles and Residence

• Contributed 200 florins (24 February 1664) toward fortification of New Amsterdam.  
• Taxed (10 November 1676) to fund the New City Dock and other debts; listed as a city creditor (1676/77).  
• Residence (1677–1686): House at the corner of Heere Graft (Broad Street) and Bever Graft (near the Market) in lower Manhattan. Confirmed in 1686 Dutch Church membership list by Domine Henricus Selyns. 

• Kniertje lived long after Claes (into the 1720s) and left a will mentioning some of the children.
