Hi,
My William Franklin Iler was born 6/15/1879 in Ill. son of Francis M. Iler & Sophronia Flack. He had 2 sisters Lucy, b. 1873 in Ill; and Mary b. 1877 also in Ill.
I will tell you that my biggest help with the Iler genealogy was from Morgan Iler on line who has a whole site dedicated to the Iler (Eilher, Eiler, Eilar, Eyler-Oyler) family. Hope that helps. his e-mail address:
miler@juno.com. Good luck.
