I appologize for taking so long to reply. Her mother was Betty Pearson, and I believe she passed away in Burnaby, BC. That's where Betty always talked about being from and I think that's where her son still lived at the time she left Honolulu before she died; so I think that's where she went back to.
I also think that for most of the years that she was alive that Bette Colleen went by the name Colleen. I knew her as Colleen and that's how her mother, Betty, referred to her.
Collen was married 3 times; her first husband's surname was Yamada; the second husband's name was Dennis Chun, and the last husband was Lum Ho - If I remember correctly, it was George Lum Ho.
