I get the slow process.
Spoke to a cousin of mine who is quite a bit older than me yesterday and she does remember Katherine who they called "Cassie".
I also discovered my grandfather's sister Margaret's maiden name whisch was "Kurila", had two sons and passed away in Ridge, NY in 2005.
I also found a "half" cousin named Dennis Smith who was born from a Lillian Mary Smith who was named Lillian Zinkarvitch for a short time. This is my father's oldest brother's kid and also confirmed by my cousin who is the half sister.
My father (and my mother for that matter) never spoke about their families when I was growing up. We were not close to any cousins except my aunt Dorothy who lived in the samre neighborhood and. of course, as a kid that's not your priority.
Getting into this, I initially wanted to confirm my Lithuanian heritage but, once you get started and the more you find out, the more it pulls you in and the more you want to know.
I never knew anything beyind my first cousins and aunts and uncles so this has opened a whole new world and I do truly appriciate the help.
