[Ger-Poland-Volhynia] Ulrich family

[Tess Roehrich]

I am looking into the mother's side of my Dad.  The names I have in that background that I cannot find information on are:
Theodore Uhrich who married Elizabeth Jangula.  I belive he was born in Russia.  I also have a Peter Reis (? from Germany) who married a Elizabeth Urich/Reis. b 8-22-1889.  Can anyone help me find more information about these people?
Thank you,
Theresa Roehrich
