Dear Kathy, I have very little info on Allen's children except through my lineage. To my knowledge, he did not have a son named Seaborn. He did have a grandson named Seaborn Louis Busby/Busbice, born about 1886 in Dooly Co. and lived in Laurens Co., moved to Jackson Parish in 1899 then to Muleshoe, TX in 1817 where he died at the age of 68. He could very well have been named after your Seaborn. Where he got his name has always been a mystery to us and still is. Sorry I can't be of more help. Wayne Busbice
