[Ger-Poland-Volhynia] Schewe

[Sieg Schewe]

I have hit the brick wall and would like some help regarding several people.
What makes it difficult there are dozen spellings for our name, main spellings-Schewe,Schiewe,Schoew,(Russian)-Webe
Peter Schewe B-Abt 1820-, Died - Abt 1878 in Siedlce, Mazowiecke, Poland
Julia (Stevens),(Stefan)Schewe Peters wife B-Abt-1818, Died Abt -1880, Siedlce,Poland
Married Abt -1853, They raised all their children except one in Justynow, Sokolow, Poland
Samuel the youngest was born in Siedlce, Poland in 1873
I am looking for better dates, locations and possible Peters & Julia's parents
Also looking for better Birth & Death date & Death location of Peters oldest son Christian.
Born in 1855 in Justynow, Poland, Died in Josephow or Lugardia (Lugartzen) Ukraine Died between 1893-1913
His wife Wilhelmine Herms B -10 Oct 1855,-D- 25 Sept.1921 in Manitoba
They attended church in Wegrow, Swat Augsburg Parish 
Peter is my G-G-Grandfather & Christian is my great grandfather
Thank You
