Hi John, For what little I know of your Josiah KNAPP and Sybil DICKERSON, I show that he was b. 1652 and died 1690, the son of Roger KNAPP & Elizabeth. Roger is listed as being a Planter & Land Speculator who was born in England and died Sep 20, 1672 in Fairfield, CT. All that I know of Sybil is that she was b. 1655 in Fairfield. I do listed that Josiah had a brother Daniel b. 1696 and bp. Jun 21, 1696 and d. 1771. Daniel m. Abigail BANKS Mar 5, 1710 and had 9 children. Hope this is of a little use - Mark
