Hello: I've been corresponding with a new found 2nd cousin re: my Magill family and I've also been looking for Allen connections. My cousin sent me some info. which, if not helpful to you, in re: to Addison Allen, it might supplement information you mightalready have. My grandmother, Lucretia Robbins Magill(Davison) had a brother by the name of William Hopson Magill. (Their parents were Sallie Robbins Zenor (of LA) and William Marshall Magill of TN). My source says that William Hopson Magill (b. 1883 in TN and died 1954) married Claudia Mae Allen (b. 1887, d. 1980). Claudia was the daughter of William Perry Allen and Joanna Bradley. They apparently lived in TN and AL and William died in Florida and both are buried in AL. I have also been told by my mother , Zenora Robbins Davison Duffy (daughter of Lucretia Magill and niece to William Hopson Magill), that there are Allen relatives that go back to VT/Conn/VA. I was also interested in your comments re: Allen's in Maury Co. TN as my gr gr aunt, Mollie Zenor Ruhm, originally from LA (married to John Ruhm Jr) also lived in Mt. Pleasant, TN (Maury Co.).The Allen-Bradley names appearing in my cousin's information may not help you but maybe there is a connection there. The namesseem to connect.
