Hi
Thank you for your responses, our relative was buried in Lodi Wisconsin, his gravestone said J R Collin A Soldier
Then the new grave in Madison has him as the first interment in 1931 and there is also an application for a veteran's headstone in 1931 his wife was put in in 1945 and then his son, daughter and daughter in law, but they have no stone only the military one, so I guess it was his wife's personal decision to have her husband's remains moved.
The only time I ever came across this was when an old lady was buried with her daughter and when the son in law found out he had her taken out and put with her husband
Thanks Glyn
