I am loking for info on Calvin--or Euclid--or Uclid or U.D. Allen. I tend to think he went by all of the above at different times or the census takers were haveing a very bad day. I find him first in the 1850 census of Marshall county Tn married to Rebecca Patrick dau of Levi Patrick from Cannon Co Tn. I next find him and his family in carroll Co Tn in the 1860 census---different first name but same birth date and same wife and children. Family members relate he was known as Calvin and died in the Civil war. Thanks for the help it is my brick wall.
