I just spoke to my stepfather and this is what he had off the top of his head.
His parents did call him Bobby.
His father was Alfred Thomas PIPES, b.Jan 18, 1907, d. Aug. 1970, Los Angeles County, California (he confirmed your info was right)
Alfred worked in the Textile industry in Rhode Island, then moved to Sycamore Illinois when Bob was about 1 year old (1941). There he worked at Diamond Wire for about 19 years before moving to Sun Valley California in 1969, there he worked for Budger (sp?) Trailer and then as a cabinet maker until his death.
Mother was Marie DURAND, b. may 10, 1915 in Central Falls, Rhode Island. I forgot to ask for her exact date of death, however it was within the last few years, she had remarried, but he also passed away before her.
Marie worked in Textiles until 1941, then at Grody Brothers in Decalb Illinois. In July of 1960 they moved to California and she worked in women's garment mfg in North Hollywood.
They were married in Pawtuckett, Rhode Island, but he can't remember the date, he said he would look it up.
Marie's father was supposedly French Canadian and she has a sister named Alice (I believe she also has another sister and a brother named Marvin as well) who married an "Ed" in 1959 in Las Vegas. They had a daughter named Dorris
Robert was born in Pawtucket, RI, but grew up in Sycamore Illinois, then joined the US Air Force.
He remembers and uncle Ernie (who he thought was the boxer, but he's not sure).
And he remembers Aunt Gertrude and Uncle James "Jimmy" PAPPAS.
Apparently, Jimmy Pappas worked as a firefighter, which was a front for his gambling business. Although he was never convicted, he was indicted by the Warren commission, when he tried to do business in New York. His brother did serve time in Sing Sing. According to Bob, Jimmy was spectacular at slight of hand and played a big influence on his interest in magic while he was growing up. He said that he could deal a hand of cards and everyone would end up with a good hand, but he would always have a better one. He remembers going into the basement and seeing a bank of phones setup and asking his dad why they needed so many phones.
While Jimmy was in the service during WWII, he gambled with his fellow soldiers and made thousands of dollars each week, which he sent back to Gertrude. Apparently, she had a gambling problem herself, though not as good at it as her husband, she lost all this money at the track.
Gertrude and Jimmy had two children, son, James PAPPAS, Jr. and dau, Marion.
Hope this helps, my email is firstname.lastname@example.org, but if you post here it will send me notification. I would love to get any further info you have.
