Winslow Genealogy

[beedub]

I have found that my ancestor Rufus Winslow (dob 1776) was born in Dartmouth, Bristol, Massachusetts and later appears in the Scipio, New York Monthly Meeting records married to Ruth (no last name). There are children, Sibil, Humpfrey, Weston, Isaac, Phebe.
Would like to know Ruth last name, her dob is 7 Sept. 1780 and death is 21 Jan 1848.
Isaac (dob 1819) is my direct ancestor and he appears in Ontario, Wayne, New York census and on grave marker in Lakeside Cemetery, but no info on his wife Margaret, etc.
Don't find any Quaker info on Isaac in the James Hazard Index.

any help out there
