I have set up a timeline for name usage.
census 1860-winkleman
1870-winkleman
1880-winkleman
1886-allen-mary's marriage
1896-allen-malinda 2nd marriage
1904-allen-harvey"s marriage
1916-allen-harry's marriage
census 1940-winkleman
It looks like they used allen when it was needed to be legal.
I don't think eli was in the service. In 1860 he was single in 1870he already had two children. Harvey was my grandfather, how I wished I had asked more questions when someone had answers. My mother told me it had something to do with an adoption?? Freda allen mckeen
