He eventually settled in Laguna Beach, California, which was - and still is - a thriving artists colony (I was familiar with Laguna when I lived in California).
Kleitsch died of a heart attack at the age of 49 in 1933. Two years later, his wife Edna opened the Joseph Kleitsch Fine Arts Gallery in Laguna which, I believe, still exists.
Note: several sources incorrectly list Kleitsch's birth year as 1885.
Unfortunately I don't know the names of the women in his portraits but I'm assuming that some were of his wife.
