The 1915 census shows Clayton MAVITY's age as 9, indicating that he was born circa 1906. Birthplace is listed as Iowa.

The 1920 census enumerates three MAVITY siblings in the Soldier's Home in Davenport: Clayton, 14; Doris, 15; and Regene, 11.

A "Mavity Family" published genealogy indicates parents and an additional sibling:
"CHARLES W. MAVITY
"Charles W. MAVITY married Iva DONALD about 1904. He died in Collander, Iowa, in 1908.
Children of Charles MAVITY and Iva DONALD: Doris, Donald, Regene, Clayton."

The 1910 census (Missouri > St Louis (Independent City) > St Louis Ward 24 > ED 459) shows the MAVITY children with their mother and stepfather:

GEORGE, John W., head, 37, 2nd marriage/less than 1 year, TN TN TN
Ivah M., wife, 28, 2nd marriage/less than 1 year, bore 4 children/4 living, IA SPAIN IL
MAVITY, Donald N., stepson, 8, IA KS IA
Doris G., stepdaughter, 7, IA KS IA
Clayton, stepson, 6, IA KS IA
Regene, stepdaughter, 2 IA KS IA

In the 1905 Iowa State Census I find Charles W., Iva M., Donald W. and Doras G. MAVITY in Valley Junction (Polk County).
