I'm looking for info on the family of Mabel Emigh & Clarence Gray. This is what I have:

Clarence found as a boarder in 1920 U.S. Census • Washington • Grays Harbor • Cosmopolis • ED# 82, dry goods salesman, married.

In 1930 U.S. Federal Census > Washington > Walla Walla > Walla Walla > District 15, the Washington State Penitentiary -- Clarence is listed as married at 20 and a salesman.

Are these the right person?

I can't find Mabel in the censuses, nor the children, but I have found death info for Donald Chester Gray and Lawrence Paul Gray. Who were the other siblings, for example?
