I am also a descendant of Drewry Allen through two of his children, Young Drewry goes to my father, his sister Nancy Allen that married John Yarbrough goes to my mother. I also descend from another Allen line in Pike County, Thomas Jefferson Allen 1803-1870 I found his grave at Century Nelson Church yesterday. I haven't been able to connect the two Allen families. I have a copy of the Allen book written by James Allen in 1965, there is a copy in the Ga State Archives also. Joe Cannafax
