Just to let you know that Deborah Long and I found each other through Jewish Gen about 4 years ago….we share the same 4 x great grandfather, Abram Leyb Lefkowicz Praszkier (about 1785 - 1846) from Stryków, Poland. It was a very exciting moment when we realised we were cousins.
We remain in touch and I know she is very knowledgeable on researching family histories.
