Perhaps if we try to find other members of Josephine's family, we might find clues about Josephine and/or Thomas after 1930?
Could this be Josephine's mother, in 1910?
Catherine Bushay, age 60, widowed, mother of 7 children, 5 still living. Living with her cousin, Mary McAbee and Mary's son, Edward.
Catherine and Mary were born in Canada French. Edward was born in New York.
They were living in San Jose, Santa Clara County, California.
