Steve:
This is the information I have been able to gather from the following:
Contact Janice Barger web site http://www.gencircles.com/users/jbrooks
Sophronia Pierce b 25 Feb 1789 Vermont d 10 Sep 1855 Hancock City, Illinois

Contact Sandra Hoyt has b as 21 Nov 1795 with no location. She is related to
Archibald Boyles b 25 June 1790, Ohio md 4 Dec 1811 Phebe Tuttle b 25 Dec 1793, Connecticut d 5 Oct 1864
Carthage, Illinois buried Old Carthage Cemetery. Put up new headstones in the past year for Boyles'.

Still looking for connection between Phebe Tuttle Boyles and Archibald Tuttle (father was Joseph Tuttle and mother, Mary ? in 1850 census Kalamazoo, MI) residing with Archibald and Phebe Boyles in 1850 Census of Hancock Co Illinois.

Michigan and Illinois census' were enumerated at different times and Archibald Tuttle is listed on them both.
