My greatgrandfather's brother, Max Karp, moved from Texas to California sometime between 1910 and 1920. He brought his wife Marine and 3 children (Ethel, Sylvan and Gertrude). In 1920 the family lived in Santa Ana, Orange County. In 1930, Sylvan and Ethel were still at home, now Los Angeles.
Ethel (1908 - 1994) married someone named Schneider in 1930 or later.
