My husband is a descendant of Dr. Christopher Columbus Welsh and Mary Ogburn Welsh. Message # 165 from Roger Lambert on this forum has info that may help you with Mary's parents. Based on this message it is possible that Hugh Edward Ogburn and Henrietta Guild are the parents of Mary Ann Ogburn. Also, after looking at rootsweb world connect, it may be possible that Henrietta married L. Miller after Hugh's death. I suspect that Mary Ogburn (widowed) was living with her daughter Helen in her later years. The SC Archives in Columbia should have Mary's death certificate on microfilm. Hopefully this will provide the link we need for Mary's parents. We are currently trying to find more information about the second daughter (Annie Welsh) of Dr. and Mrs. Welsh. She married Robert Long, son of George (or William) Washington Long and Sarah Matilda Adams (Ellis?) Long. We are stumped on Robert Long's parents, especially the Long family.
