Mary - Byrd/Bird is not a nickname, it was passed down in
these families for some reason. Bird Pate was b. ca 1790 in Montgomery Co, VA, d. 15 Jul 1843 in Independence Co, AR. He was in Jefferson Co, TN in 1830 and 1840, in 1850 White Co, AR, his widow was listed as R Caruthers - she remarried to Samuel Caruthers on 23 Feb 1844. His marriage is recorded in Jefferson Co, TN - 17 Feb 1814, Bird Pate to Rebecca Hankins. There is a Letter of Administration dated 30 Oct 1858, recorded May 1859 in Independence Co, AR showing Bird Pate d. 15 Jul 1843 and lists his heirs. Hope this is of help.
