I realize this is >10 years later than the last post on this thread, but there may still be some interest.
As you pointed out in another message, there is a lineage from James Cate all the way up to Adoniram Cates (b1784), and his son Seth born Aug 5 1812 in Avon, Maine.
Tim Booth indicated that this Seth married Sarah Sally Nevins Cushman and lived in NYC until at least 1880.
In fact I think this is wrong. Seth (my Great-Great-Great Grandfather), moved to Canada, settling in Wakefield where he married Mary Link and established a Cates line in Canada. He died in 1880 and is buried in Wakefield Quebec. Several census records in Canada indicate that he was born in the USA, and we have his birth date as February 5, 1812 in Avon, ME. His headstone reads: "Died 27 Aug 1880 age 68 yrs 6 months.
Genbug5 indicated in his message that Seth Cates was born in Kent England, moved to Canada, living in Wakefield where he married Mary Link. This is clearly wrong.
It would be nice to clear up these different reports about Seth.
