MiniMansfield on Family Tree Circles

Looking for Samuel A Mansfield b. circa 1904-1971 p.o.b presumed Lancashire & any possible siblings & his parents.
Samuel married Olive M Stroud b.1907 p.o.b Lancashire & marriage of the same area possibly in 1932.

Samuel & Olive had four sons. One of which was my grandfather, Harvey. Any info on the families of the others would be greatfully appreciated....

John b. circa 1929
Christopher b. circa 1930
Harvey b. 1931
David b. 1947

Information on Samuel's parents would be superb... :-D
