I believe you can find Christian and Mary Reinhardt in Coweta Co, Georgia in the 1850 census. The family is as follows:
Christian, age 40 Mary A 25? John 10 Mary H 8 James 7 Martha E 4 Eugene 1
In the 1860 census they appear in Atlanta, Fulton Co Georgia as follows:
Christian 50 Mary 35 John M 20 Fannie 18 Elizabeth 14 William E 7
Other researchers have indicated that Christian died in Atlanta in 1881, but I have not been able to confirm this or locate a burial. Others have also identified his wife as Mary McTyrre, but I cannot contirm this either.
