[Ger-Poland-Volhynia] Place search: ''Rumunki Sierpeckie'' in Sierpc county, Russ-Poland

[BirgitSteinke&GerhardAJabs]

Hello all,

Julius Leopold Jabs, who was a younger brother of my great-grandfather 
Eduard August Jabs, was born in Ossówka near Sierpc on September 4th 
1865 and died in Rumunki Sierpeckie on July 5th 1899. Also his son 
Robert Jabs was born and died in Rumunki Sierpeckie on March 22nd 1898.

I did not find this village in the Sierpc county.

I've used the ShtetlSeeker of JewishGen, "Slownik geograficzny 
Królestwa Polskiego i innych krajów slowianskich" 
( http://www.dir.icm.edu.pl/pl/Slownik_geograficzny/ ) and 
Jutta Dennerlein's UpstreamVistula.org .

Perhaps it might be "Rumunki", which is between Jaworowo-Lipa,
Rzeszotary-Zawady, Ostrów, Rzeszotary-Pszczele and Rzeszotary-Chwaly. 
This area is few kilometers NE of Sierpc.

Any help, comments and suggestions would be greatly appreciated! 
Thanks a lot!

Gerhard
