The profile of Roelof Helmigs Van Houten (Helmicks-2) links to Roelof's 2 children by his first wife, Aagtje Vreeland (Vreelant-1). It links to his second wife, Feytje Sickels (Sikkels-6) but doesn't link to any of his children by her. William Nelson, in his History of the City of Paterson and County of Passaic, lists the following children for Roelof and Feytje on pp. 238-239:
1. Robert, died Jan. 27, 1786, aged 74 yrs., 16 days; married Elizabeth Post. Nelson has a transcript of his will on page 239, citing EJ Wills, Liber 29, fol. 500.
2. Cornelis, b. Jan. 16, 1715; married Rachel Post
3. Johannes, b. June 6, 1717; married Catherine Cadmus. (I disagree with Nelson on Johannes' wife, and argued in the article "A Tale of Three Johns" published in New Netherland Connections, I forget which issue, that this Johannes Roelofse Van Houten married Lybetje Van Riper. Nelson says that Johannes Roelofse son of Roelof Cornelisse VH (Van_Houte-22) married Lybetje, while Herbert S. Ackerman in his Van Houten Family has Lybetje married to Johannes Roelofse (Van_Houten-67) son of Pieter Helmigse VH (Helmicks-1),)
4. Jannetje, b. March 19, 1719
5. Geertrui, b. Jan. 20, 1721, m. Hermanus Van Wagenen
6. (prob) Feytje, m. Johannes Cadmus
7. Catalyntje, b. June 26, 1726; m. Frans Post
Of these children, five of them (all but Jannetje and Feytje) in addition to Helmigh and Aagtje (his children by his first wife) are named in the will of Roelof Van Houten, dated June 16, 1762 with a codicil dated July 6, 1769 and proved Dec. 1, 1770, recorded in E.J. Wills, K, 294. Nelson gives a full transcript of the will, but not the codicil.
