I have been working on the Jednoralski family tree for several years, but have done more in the last year. I have my line traced back to Jacobus Jedoralski, born in the 1750's. I have bites and pieces of other Jednoralski lines. I am trying to tie them all together. I have entered several public trees on Ancesrty.com. I have some information on Hedwig Baranski, under a tree which starts:
Buffalo, NY 4 - Jednoralski.
