I am researching the surnames SOLOMYACH and YABLONSKY

from Courland. I am not sure what town in Courland.

I am supposed to be related to Abba Eban through the
surname Solomyach which was shortened to Solomon.
Also one of my Yablonsky ancestors was according to my
great grandmother the rabbi of the community where
these two families came from. Does anyone have any
information or know where I can find any information
pertaining to these families? Thank you.  
Sincerely
Matt Schrier
