I have a few relatives from Saline, Washtenaw, and I'm at a loss how to go about looking up records for them!

Albert H. Wright b. 29 Jan 1825, Saline

Harriet Brown b. New York

Helen Almira Wright b. 18 Apr 1850, Saline
m. 18 Nov 1870 Ypsilanti, Washtenaw
John Charles Shier b. 29 Dec 1845

What types of records should I be looking in, what places should I contact, for these years? Thank you!
