Thank you for sharing the trees with me.

I have one more question... as i'm filling in details on my father's side, how do I capture alien #'s from when people immigrated to the US? Example: Frank Pesko immigrated to the USA from Carpathian Mountains in Russia in 1911. His alien number is 196994. I want to capture this detail, but i don't know how.

thanks,
Tia

her earlier message:

Hello! I stumbled across your family tree and was wondering how i can add on to it? I just joined Geni because i found this family tree, so forgive me for being extremely new to it.

Barbara Jean Padgett is my grandmother. I'm the daughter of her second daughter Tia (DeFrees) Pesko (listed as private). I'm not on the family tree. For whatever reason i never seem to show up on these things. Not sure if it is because there was issue filling my birth certificate or if people are tricked because my mother and i have the same name

NOTE: so with GENI I once again come in contact with one of the descendants of the Emery/Hardesty line. I may have had contact with her grandmother years ago when doing the Emery book: Judith Elaine Burns, Compiler, Revised Genealogical Records of The Descendants of John Emery of Newbury, Massachusetts, The, 1982, Gateway Press Inc. Baltimore, Md. / Transcript 1982-?, 82-83136 Library of Congress. Revised from the Genealogical Records of the Descendants of John and Anthony Emery of Newbury, Ma. (1891) Rufus Emery. and also my Judith Elaine (McKee) Burns, Thomas Hardesty of Greene County, Indiana His Ancestors and Descendants, Transcript.

To me this is what GENI is all bout SHARING and FREELY for me hoping to re-gain contact with those who I done research with pre-1990 if still alive and if not one of their descendants or relatives
