Hi, I'm Ashley Lampkin, sister of Alyssa Lampkin; I am online trying to find out this same information.
My grandfather (Robert E. Lampkin) was adopted by Mr. & Mrs. Dewey O. Lampkin.
Adopted mother later re-married as her name,Mrs. George W. Lauersen,is stated in a wedding announcement (a newspaper clipping) for my grandfather, Robert Edward Lampkin and my grandmother, Delia Louise Hatley who wed in San Antonio, TX. From what I gathered most of the Lampkin(s) have resided in San Antonio, TX...my father, his dad, my uncle...so I will continue my search on the family history. Thanks
