Very much so!
You and my husband, Greg, are 3rd cousins, once removed. Harry & Irene are his 3rd great grandparents. George Parnell's sister Mabel, the only one who was born while they were in Kansas following the civil war, raised my husband's grandmother. She grew up in the Tarrytown area too. My mother-in-law was born in Hartford, where her grandmother lived.
So sorry about your dad's recent passing.
I would love to share information - in fact I sent you an invitation to view my tree with no restrictions for living people, so you can see the information and photos for everyone. Send me an email if you'd like to share family tree information. firstname.lastname@example.org
