Virginia Young LaRocca is Diana’s grandmother. She started out life as a Mormon in Utah, but somewhere along the way became a Christian Scientist. She is listed as “Chr. Sci.pr.” (Christian Science Practitioner) in Los Angeles telephone directories in the 40 and 50s, and listed with her own telephone line.
A Christian Science practitioner is an individual who prays for others according to the teachings of Christian Science. Treatment is non-medical, rather it is based on the Bible and the Christian Science textbook, Science and Health with Key to the Scriptures (1875) by Mary Baker Eddy (1821–1910), who said she discovered Christian Science in 1866 and founded the Christian Science church in 1879. According to the church, Christian Science practitioners address physical conditions, as well as relationship or financial difficulties and any other problem or crisis.Wikipedia definition
A 1955, an LA telephone directory lists a Ned J. LaRocca at 4414 N. Ethel and a Virginia Young LaRocca with the same address.
Donna Cotterell is listed with the 13055 Moorpark address. 13055 Moorpark is on a corner with Ethel St.
4114 Ethel St. doesn’t seem to be an “real” address; I don’t find a record of it anywhere besides the phone directory. This could be a result of the house modification for Donna, Diana and Constance.
1957 Virginia Young LaRocca is listed in the phone directory at 4414 N. Ethel State 4-7052 North Hollywood. Cr. Sci. Pr.
The Christian Science Church won the right to accept insurance for their practitioners, but I have been unable to find what year.
I can’t tell how much income Virginia made from her vocation as a CSP.
It is probable that grandfather Ned LaRocca was the primary breadwinner of the household.
I’m sure Donna received child support and likely alimony as this was the norm of the era.
