O’Brien and his wife divorced. When she remarried, the kids took the stepfather’s name.
According to Wikipedia, “Gilpin was born on September 26, 1966 to Wes Gilpin and Barbara Bushway. He had three sisters: April, Pattie, and Peri Gilpin.”
It looks like Marc and April were born to this couple, while Pattie and Peri were born to Jim O’Brien (real last name, Oldham) and Sandra Oldham whom he later divorced. She married Wes Gilpin, and the two sisters took his name. Wes apparently divorced Sandra or she passed away, and he married Barbara Bushway.
I’m glad my parents just married each other and stayed that way.
Out of the 4 children, only Peri survives. One sister died of natural causes at home, the other of cancer. All three of her siblings died before age 60.
What a lot grieving for the younger generation in a family tree.
And O’Brien was an assumed name anyway. His real last name was Oldham. He adopted his new name when he was a radio dj.
