I am not sure if this is relevant, but grave relocation details often only
removed the skull and larger bones in the 19th century. Where coffins were
not present, entire legs and arms were left behind. This certainly was the
case at the Little Big Horn battlefield and it happened at the 1846 San
Pasqual Battlefield here in California. The latter burials got relocated to
Old Town San Diego in the 1860s and then again to Point Loma in 1880.
