San Fernando Valley abbreviated SFV.

The newly released 1950 census gives us

more information about the LaRocca/Cotterell family unit: they are listed at a residence in Gardena at 1830 W. 147th.

Joseph’s occupation, Radio Orchestra Manager, Virginia, Christian Science Practitioner, Donna has an empty box for occupation, granddaughters Constance S. is listed as 7 years and Diana L. as 5 years.

The above is an online phone directory from Gardena 1951. It has a listing for Virginia LaRocca, CSP, at this same address but no Joseph is listed. Why no Joseph and Virginia listed together, as every other year for decades in directories and voter registrations.?

When did Diana and family leave Los Feliz? late 1940s?

Yes probably

How long did they live in Gardena?

About two years.

When did Diana and her family move to 13055 Moorpark St. in Studio City/Sherman Oaks?

I first connected the family to 13055 Moorpark St. address by an online city building permit dated in Dec. of 1952.

This house on Moorpark Street was located on the west side of Studio City close to the eastern border with Sherman Oaks. Specifically, off of the intersection of Coldwater Canyon and Ventura Blvd.

The Los Angeles River is nearby the house as is Sportsman’s Lodge; a classic Hollywood and SFV landmark.

The family knew about the area in the SFV for some time because Joseph’s only sister Kathryn Marinello, and her husband Anthony opened a food store at 13251 Moorpark in 1947.

There is a 1947 City document I have been unable to download; indicating a “food store” at 13251 Moorpark St. The building was not owned by the Marinellos.

Meanwhile……Diana’s father Robert Morgan Cotterell also moved to the SFV around this time, but further west of his daughters and ex-wife. His new wife Patricia/Pat and their two children, born in 1950 and 1951, (while his first 2 daughters were in Gardena according to the 1950 census) start out in the Canoga Park/Winnetka area on Lurline Ave.  

It’s the first of many moves for them around Los Angeles due to Bob Cotterell Sr.’s career at Douglas Aircraft.

It is unknown exactly why the The LaRocca/Cotterell family moved to the SFV, but we do know that they were part of a massive migration to the area after World War 2, from both inside and outside of Los Angeles.

“The end of WW2 transformed the Valley and vastly accelerated its growth

with: vast tracts of suburban housing, shopping centers and industrial parks where chicken ranches, orchards and cattle ranches and wheat fields once existed. The 1940s and 50s, when I was growing up, the Valley was full of movie cowboys, beautiful ranches and fine horses.”  

Jerry England at cowboyup.com

“In the five years after the war, the population (of SFV) more than doubled to 402,538 residents-the pastoral San Fernando Valley was suddenly the ninth-busiest urban area in the nation. Valley society was a mix of young suburbanites, older families who had come west to try their luck as engineers, animators, or pioneers in the new field of television, and ranchers trying to hang on in the face of the new hordes.”

The San Fernando Valley: America’s Suburb by Kevin Roderick

 I discovered that Ned LaRocca spent most of the 1950s working as an orchestra manager for composer/conductor Leith Stevens, through Ned’s death certificate.

I can confirm two Leith Stevens projects that have a credit as “contractor” for Ned LaRocca: A Doris Day album recorded in 1951 at 1032 Sycamore Street; a studio known at that time as “The Annex.” Found on youtube.

The website careerexplorer.com defines an orchestra contractor is:  “He or she has the job of finding the appropriate musicians for Broadway shows, television episodes and commercials.”

Ned already had experience adapting to a new mass medium when his first industry Vaudeville, died in the early 1930s during the Great Depression.

One significant factor that changed the popularity of radio programming was the rise of TV in the 1950s. Drama and comedy and musical variety shows moved to TV.

In 1950, just under 20 percent of American homes contained a TV set. Ten years later, nearly 90 percent of homes contained a TV—and some even had color TVs. The number of TV stations, channels, and programs all grew to meet this surging demand.

Ned LaRocca also has a credit on Leith Steven’s 1953 score to the Marlon Brando movie “The Wild One.”  The Los Angeles recording industry was growing by leaps and bounds in the 1950s.

This record was a hit, released by Decca records, it remains Leith Stevens most well-known and well-regarded creation.  J. Ned LaRocca is credited as “Contractor” on the project. Per Discogs.com. As I understand, it was the first soundtrack entirely made up of Jazz music.

Besides composing and conducting “The Wild One” soundtrack, Leith Stevens composed numerous scores for radio shows, movies and  T.V. from the 1930s until his death in 1970.

 IMDB indicates that many of Stevens’ compositions go uncredited as “stock music.”

More on Virginia Young LaRocca,

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. Read more about her early years as a vaudeville performer in the family history chapters.

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.

In 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.

At some point, the Christian Science Church won the right to accept insurance for their practitioners, but I have been unable to find exactly what year.

So, I can’t tell how much income Virginia might have earned from her vocation as a CSP.

I’m sure Donna received child support and likely alimony as this would have been normal for the times.

However, it is probable that grandfather Ned LaRocca was the primary breadwinner of his household.
