Hi I am trying to trace Nelson Wright, a sibling of my 2 x great grandfather, who was born in 1825 in Alder Creek, Oneida, NY but who sometime after the 1860 census left NY state and is thought to have gone to Louisiana. By the time of an 1871 family land transfer he was presumed to be dead. I have tried find a grave for him and also the Louisiana online death records. Does anyone have any idea how I could proceed to search for him? I realise this is the time of the Civil War. Is it possible he went to fight in Louisiana?
