Caleb Osborne - Caleb's father

My daughter and I have DNA markers connecting us to the Osborne's of Ashbury, Kent, England. If Caleb was born in Elizabethtown, New Jersey, as some suggest, then his father would have likely been a relative of Thomas Osborne of New Haven Connecticut. It's too coincidental that Ashbury, Kent Osborne's were living in Elizabethtown when Caleb was there as well. We just haven't been able to identify who his father is yet. Caleb is my confirmed 5th great grandfather. We're looking for clues.
