Hi, I'm not sure if this will help, but Mr. Chamberlin may have been one of the two brothers of John G Chamberlin. John is in my line and had no children named Lydia, but he had two other brothers who could have married - William Chamberlin, III and Aaron Chamberlin. William was born in 1808 and Aaron in 1812. Their father was William Chamberlin Jr born 1771 in Hunterdon, NJ, married in NJ but moved to Michigan and died there. I know they were in Michigan by 1828 as that is when my gr gr gr grandmother was born. But I am not sure when they came. John Chamberlin was married to Rebecca Wilson and both are buried in Oak Hill Cemetery in Bloomfield, Oakland County, MI. - as is their father William Jr. and his wife Nelly (nee Sutphin). Let me know if any of this helps. Sylvia Link
