Yes Otis was born in the Grapevine TX area . Probably in Denton Co just a few miles from Grapevine in Tarrent Co TX.The whole family is on the 1900 Denton Co. tX census . They apparently left after Grandpa Alexander was killed, and they went to Mt. Plesant TX , Titus Co and lived there several years. They were on the 1910 Titus Co TX census there. There was lot of Allens that lived in this area , do not know the connections yet just getting started on my Mother Ruby M Allen's line.
