I am looking for the descendents of Robert D. Allen, son of R.T.P. Allen. Robert D. Allen married Laura Sims of Bastrop, Texas, and by 1887 had only one surviving child--Robert Sims Allen.R. D. Allen's second wife was Minnie Green, but they had no children.R. D. Allen served in the 17th Texas Infantry, CSA, and was for a time the superintendent of Kentucky Military Institute.One source said that he died in Houston "a broken man."
