Vera I'd have a look at http://www.many-roads.com/genealogy/documents/Prussia-Germany/Adressbuch%20P osen%201898.djvu give it time to upload. And in the book Naturalized Jews of the Grand Duchy of Posen in 1834-5, E.D.Luft (2004), there are 9 possibilities. One Blaschhauer from Murowana Goslin, Poland 2 Blaschker from Ostrowo And the rest Blaschke from Rawicz 4, Schonlanke 1, Kozemin 1. Blaschke and Blachker seem to be used interchangeably for the same person. And in Kempen, Posen, Prussia (now Kepno, Poland) I found in BMD records 3 Blaschke and 4 Blaschker who married female Silberberg and female Simon; One of the former was born in Schönlang. These BMD cover 1825-47 only. Most were birth records 1832-1945 born in Kepno. Arnold In New Zealand 1. Bleschke- Schwiebus & Bialystok (Vera Miller)
