In the 1880 U.S. Census, Henry (as well as his wife, Christina, and daughter Emma) is still listed as Gran (I don't know when he changed the surname to Grant). You can see them in lines 38–40 of the Ramsey, MN, tally below. (Also listed on line 41 at the same address is "brother-in-law" C.E. Kilberg, but it is unclear whether he is really related.) Henry Grant is Elliot's great-great-grandfather.
