Interesting post concerning their grandson named Cyrus.
Do you know where when Gilbert G Dart was born or do you have any source information on that?
I'm curious if you have any links to Gilbert G Dart and Mary Cook? they are on a land sale together in Fabius NY in April 1825 and Mary Cook is apparently the widow of Ichabod Cook.
In a Kilbourn Geneaology published 1856 by Payne Kenyon Kilbourn page 213
31. Capt. Jonathan Kilbourn
70. Mary, b. east HAddam Conn., Sep 10 1767; m. Dr. Silas Dart of Chatham. After his death, she m. Mr. Cook, of Middletown Conn.
Also in Early Connecticut Marriages records of the First Congregational Church of East Haddam we see a record for __________________Dart of Chatahm m. Polly Kilbourn on 4 Dec 1785.
I am very curious if Silas may have been misinterpretted from Cyrus in the Kilbourn work?
