Seeking info on 2g grandfather Luther Riker, born about 1809 perhaps in New Jersey and perhaps with sibling Amanda Riker who married a Penn. Luther was in Michigan from 1839 in Lenawee/Hillsdale/Jackson counties and later in Gratiot and Isabella counties. Was married to Julia Kelley until she died in 1850; then married to Louisa McGuire. Cannot find any birth or death info on Luther. What do YOU know about him or his family?
