After several visits to Family Search, WikiTree, Findagrave, etc. and looking at census, I realized that Eva's oldest children would have been born before 1930 census, so finally just now found the 1910 census with Thomas and Jenny (Ellen Virginia) Brewer's family on it, and there is Eva Brewer Girtman as well as several others, I was not sure were siblings, listed! Thanks for pointing me to this handy tool!
