Searching for family members

I am searching for family members from the Houston, Texas area. My father is getting older and we have been trying to search for family members. The only names I know are Maurice Collins, Betty Jean Collins and Michael. If anyone has any information, we would appreciate it. My grandparents were Ruby Wilson Harper and George Harper, Jr. My parents are Carlton D. Harper 09/15/49 and Pamela M. Williams 03/20/53. My grandfather passed away when my father was 19 and grandmother passed away in or around 1990 in Oxnard, Ca. I remember when I was a child, we visited in Austin Tx. I had an uncle that had a wooden leg. The rest of the memories are just gone out of my memory bank. I dont have any other info.
