Since there appears to be two possible WDA Bird's I will give the following: William David Arnold Bird, son of Mark Bird and Mary France, was born January 1. 1846. He married Catherine Dockery and they had: Martha Colone Bird born Jan. 29, 1868; George Washington Bird born in 1870; Julia Bird born Feb. 2, 1872 (this is my great grandmother) Nannie Bird born March 26, 1874; Sarah Melissa born January 24, 1876. The last baby and catherine died close together then WDA married Lizzie Ottinger, the daughter of Michael Ottinger and Elizabeth Winter. They had Dora E. born August 8, 1881; Essie Lorena born April 9, 1883; James Augustus born October 28, 1884; and WIlliam Calvin born OCtober 1887.
I hope this will help to clear up some of the confusion.
