CONRAD in Magdeburg

Looking for information on the family of Carl Maritz CONRAD, born in
Magdeburg on January 21, 1820. He married Elizabeth Cabos from Lippehne
in 1849 and had these children:

Elizabeth Conrad, born January 15,1854
Bernard F W Conrad born April 26, 1856 (born in Gheifenhagen?,Pomerania)
Albert Carl Conrad born August 7, 1859
Edmund Herman Frederick Conrad born November 2, 1865 (born in
Polzin,Pomerania)

They came to the US (Wisconsin(Milwaukee) by way of Pennsylvania.

Any information would be appreciated
