Donna Virginia LaRocca Cotterell marries John “Jack” Holroyd in Las Vegas on October 3, 1958, per online Vegas wedding records very difficult to decipher. Found on ancestry.com.
Patriarch Joseph Ned LaRocca dies of lung cancer towards the end of 1959.
Ned LaRocca’s grave is in Glen Haven Memorial Park in Sylmar.
Below are closeups of Ned LaRocca’s death certificate. It looks like he spent about a year in a sanitarium located on Foothill Blvd. in the Tujunga/Sunland area. It was called “Lakeview Terrace Sanitarium” and the building was originally the home of silent film star Francis X. Bushman.
I have been unable to learn if this was specifically a Christian Science sanitarium, (his wife was a CSP) but I have learned that the Tujunga area was considered to have cleaner air than other parts of the San Fernando Valley.
