I am trying to locate descendants of Chris & Sarah Columbus who lived in Lavaca,TX. The town's name was later changed to Port Lavaca, TX. They were the parents of: Hubert, Roland or Rolland,William & Eatenton. My grandfather was Roland and he was the father of: Dorothy,Velma,Christopher,Horace,Georgia and David, who was my father. My siblings and I never had the opportunity to meet my grandfather's brothers, only other grandchildren who were unable to help.
