After seeing your post this afternoon, I spoke to my mother and although the name Nina Jarvis meant nothing to me, my mother immediately recognized it as her grandmothers maiden name. She is delighted that we may have finally found some relatives from her father's side.
Assuming all of this is correct and it does seem so, you have three generations of relatives living mostly in the Pittsburgh area. Alfred married Betty Foley (Folan) who came to the U.S. from Ireland in the 1920s. They had two daughters; Anna Mae (Nancy) and Marylou. Nancy is my mother and she and my father (David Regan) had nine children of which I am the oldest. There are 21 grandchildren spread among my siblings and I. Marylou married William Darragh and they had seven children who have produced approximately 18 grandchildren.
My mother and I (as well as the rest of the family) would love to know whatever you can tell us about the Greenings and your part of the family. As I said we live mainly in the Pittsburgh area in Pennsylvania. Where are you from and what other areas do you know of relatives residing. Please tell us as much as you can about past and living relatives and we'll be happy to let you know about us.
