Maggie - I just came across your quert about the Decker family in Michigan. I have a record of George M. Decker b 1852 who married Carrie Howe. This couple had children Goldie and Glenn C. Decker. George was the son of Aaron and Elinor McLain. I have information on this family if you are interested. Carolyn I descend from Aaron through their daughter, Melinda, sister of George.
