I need some help

I'll probably end up outing myself with this but I need some help.

I'm looking for some people from my past. People of Colorado. Denver (or the suburbs) thereof.

Wanda Harvey (remarried sometime in the 80s and I don't know her new last name. Husband was a truck driver). Had two kids I knew of: Cynthia (Cindy) Harvey and John (or Jonathan) Harvey. Once married to John Harvey. Lived in or around Denver, CO. I stayed on the family farm some time between 1977 and 1979 while my mom was in jail in Utah. Wanda came to Utah in or about 1982 to visit my mom. That's the last time I saw her.

Doug (or Douglas) Coles. Also formerly of Colorado but I don't know if he was born there, passed through or what. Visited Utah in the 70's sometime to get my mom to sign their divorce papers. Said "it's hot enough to fry and egg in here" to my mom. That's my last recollection. He was not my bio father, but he might know who is. At the very least, he can shed some light for me on my mother.

Virginia or Penny (maiden name Risher). Allegedly sisters of my mom. I believe she had five sisters. I've never met them. These are the only two names I remember. I also believe that the parent's names were Leona and Don or Francis. I'm unsure. I believe the grandparent's name was Ferguson (unsure on spelling).

Anyone know of anyone who might know of these people? I've checked the social security death index and to the best of my knowledge, they're not dead yet.
