I've reached a sticking place in my Joslin line. I can trace back from Hartley Joslin, to James E Joslin, to Reuben Joslin but there the trail goes cold. I can see from the 1850 census that Reuben was born about 1817 in NY. His father and mother are also from NY. His wife Sally and her parents are also from NY. I cannot seem to find more information further up the family tree. Can anyone help with this? I would be very greatful for any leads. Thank you.
