On the ancestry.com 1920 census, there is only one Rose Higginbotham in the northwest.
In Oakland, Oregon.
Head of household is Thomas E. Higginbotham. He is a widower.
Children are:
Forrest E., Rose L. age 13 in 1920, Myrtle A, David T., Arthur C. and Mildred K.
But this may not be the right family, just a guess. Rose would be 17 in 1924, so there it could be a match.
There is no death index for Washington State from 1908-1939. So that is a dead end for searching.
