I'm researching American composer Henry Cowell (1897
-1965). The 1910 US Census (dated May 11, 1910) lists him
and his mother, Clara, living with relatives, Walter D.
(29 yo) and Jennie (52 yo) Guilbert in Collyer Township,
Trego County, Kansas. The document lists Walter as a
farmer and includes neighboring families headed by
Gustaves Johnson (46 yo) and Peter Keller (37 yo).
Any information, however trivial, is useful - including
local churches, landmarks, schools.
I have a PDF of the census document I can e-mail if you
are interested.
