Has anyone done any work on the Rapp's of Chicago?
My mother Diane, 2 brothers Frederick R and Robert F. Came from this group (Particularly Robert Arthur who was a twin of Harry) Clifford F. Rapp - Born June 15, 1892 Elmer August Rapp - Born Feb. 13, 1896 - Died April 22, 1925 Anna D. Rapp - Born Nov. 3, 1897 Helen M Rapp - Born - Oct. 9, 1899 Robert F.

Does anyone have lineage beyond this? Thanks in advance.
