Andrew Davison b. abt 1806 in Connecticut

Looking for the ancestors of Andrew Davison. He married Sally King (possibly in Delaware County, Indiana in 1837).

Children: 

George b. 1839
Nancy b. 1842
William b. abt 1841
James b. 1845
Sarah b. 1851
Nellie b. 1857

Settled in Macomb County, Michigan by 1833 and then moved on to Clinton County, Michigan in later years. Not sure where he was born in Connecticut. Not sure if he had siblings. There is another Davison that was married the year before in Delaware County, Indiana. Hoping that there was a link between them, but there doesn't appear to be. No death record for Andrew and I'm not entirely sure the information on the headstone is correct.
