I am related to a Thomas Allen who lived in Beaufort Co., NC until 1835.He is know to my family as Thomas, Sr.He married Elizabeth "Betsy" Ecklin in 1807.They had at least 10 children: Ashbury, Walter, Mahala, Isaac, Jeanette, Jeamsie (also called Fanny), Beth, Sallie, William Henry, and Thomas, Jr.
Thomas, Sr. and Betsy moved their family along with most of Betsy's brothers and sisters from Washington, NC in Beaufort Co., to an area now known as Cordova, TN outside Memphis in Shelby Co. in 1835.The others with them included the Ecklins, Patricks and Galloways.
Thomas, Sr. was born on 23 January 1787 in Beaufort Co., NC and died in Shelby Co., TN on 16 January 1848.Betsy Ecklin Allen was born on 24 October 1789 in Beaufort Co., NC and died in Shelby Co., TN on 27 December 1858.
Thomas, Sr. was the son of Walter and Jemina Pearce Allen who married on 14 December 1782.Besides Thomas, their other children included John, Walter, and Jemina.Walter's father was John Allen, and he had a brother John and a sister Sarah.Betsy's parents were Joshua and Sarah Ecklin who married in Ireland and moved to NC before 1779.
My family descends from Thomas, Jr.I do have some information about the other children of Thomas, Sr. but would always like more.As for going back to predecessors, this has been highly difficult for the various family researchers because the family had the habit of naming each first born male child John.We believe that Walter's father was the son of another John Allen and that this John Allen had two other sons named Shadrack and Joseph whose first son were each named John.All in all making the John Allens hard to distinguish.
If this appears to be the information for which you were looking, please let me know and I can send you more information about my line and other Allen researchers along these lines.
