I may have something for you and maybe not.
Your note that you thought possibly that Judlow Cranker father might be John or Nicholas Cranker (or variation thereof) I found a John Crankheyt born about 1749, son of Jacobus Crankheyt and Margaret Busch. But uncertain about connection to Judlow. Also a John Krankheyt born 1739, wife Deborah Kenny, son of Theunis Krankheyt and Annatje Van Tassel. Again.. no lead on children of John & Deborah.
I believe both of the above would lead to Herck Siboutszen Krankheyt & Weyntje Theunis Cray .. Sleepy Hollow Dutch Reform Church records.
Judlow or Judlof name is a puzzle and is part of the problem. Dutch to English names. Sounds like...?
