I think I have solved the problem of which line the Loyalists in Ontario, Canada, came from! An Abraham, John, and William show up in Ontario, Canada, in 1785.
I believe they were the sons of Willem H. Krankheyt and Maria Elizabeth Stickle, who were married in 1745 in Dutchess Co., NY. According to the baptism records of the church at Red Hook, William had sons John, Abraham, Nicholas, and Wilhelmus.
The only Krankheyt that I can find in any spelling who has sons by all three names, Abraham, John, and William, is Willem H. Krankhheyt above. I believe Willem was the son of Herck S. Krankheyt and Fytje De Ronde and the brother of my ggggg-grandfather, Hercules Conkright, who ended up in Kentucky.
I am basing this on the fact that Willem (bap. 1718 in the Old Dutch Church of Sleepyhollow, Tarrytown, NY), also had a brother, Sybout, baptized in the same church in 1716 AND 1) An Abraham, John, and William Cronkhite (aka Cronkwright), appear in Ontario, Canada, as Loyalists along with their mother, not named, a widow, in 1785, AND Abraham stated that he was from Albany, NY. Another Loyalist, Sibert Conkwright, also tried to claim that he left Albany County, NY, the same year as Abraham (1777) AND Sibert's widow, Mary, came to Canada the same month and year as Abraham (March 1785).
Lots of info. to tie together, but in the FREDERICKSBURGH BAPTISMS from http://my.tbaytel.net/bmartin/mcdowall.htmhttp://my.tbaytel.net/bmartin/mcdowall.htm an Abraham Cronkheet married Mary Kail and had a son - Nicholas bap. 3 Aug., 1800 (Nicholas was very likely named after Abraham, John, and Willem's other brother, Nicholas, who was bap. in 1754 in Dutchess County !!!)
