I have hit a brickwall trying to research my GG Grandfather. The first census I can find him on is a 1900 census. It says he's from Indiana and I've even went through the ENTIRE census for that county on the next decade after his birth in 1861.
His name was Rosen Delmain (other variations I've seen are Roson Delmane and Rosan Delmayne). He was born around 1861. His exact birth year changed from census to census. His death certificate says he's from Logansport Indiana and I have several census' saying he is from Indiana. His parents are listed as unknown on his death certificate. Delmain is a very uncommon name and every Delmain I have found trace to him and his wife Mary Brown of Catawissa, MO. The first record I find of him is an 1883 marriage record to Mary Brown in MO. Then a 1900 census is the next record.
What other avenues can I look at to try and track him down?
