Possibly. I found my Great Grandfather there which opened up my Katz kine considerably. The books follow the lineageof Saul Wahl who was King of Poland for one day. It covers many of the famous Jewish families of Europe extending out into South Africa, Austraia and other countries. I would recommend that you borrow it from your local library and see if you have a connection before buying it. BTW I misspelled it. It is Unbroken Chain.
OK, Zvi Hirsch Alprsh was Born in Posen. Joseph Apter died in Posen. Aryeh L Barnett or Lichenstad was born in P. Alfred Abraham Barnett was born there, Benjamn Benas was born and died there. Saul Berliner wa Born in P. Joseph Casas died there, Jacob Gunzburg was born there as was Aryey Lieb Haim, and Isasachar Baer Litchenstad Yehudah Loew was born and died there. Abraham Mirels died there as did his half brother Baer Mirels (different mothers). Rebecca Phillips was born there as was Heinrich Count of Radenz as was Charlotte Cheindel Sherach. That is my lit. I got most of my information from Neil Rosenstein's The Unbroen Chain. Thanks
Who in your family is a Henderson? Sounds as though you are European descent.
I have traced my Hendersons back to approx. 1775, in Milnathort and Kinross in Kinrosshire. The Highlands in Caithness are full of Hendersons but I know of no connection.
I don't think there is a way to search a specific group on GenealogyWise, but if you use the general search box at the top of the page you should be able to see if there are any matches to posts in the Scotland and Scottish Ancestry group.
The surname list on the Scotland and Scottish Ancestry group is a set of hyperlinks to other GenealogyWise groups that relate to Scottish surnames or locations. If you know of a group that you think should be included on this list please send me a message to let me know and I'll be happy to add it.
