What I know about Ellender or Eleanor/Elin Allen is that my Levi Wooldridge married her in 1851 in Hamilton County, IL. She died before 1879 when he applied for pension. They lived on a farm in Thackery, Lassiter Twp., Hamilton Co., IL. In the 1860 Census, she is listed as being born in KY. I believe this may have been the second marriage for both her and Levi. There are many Allens in Hamilton County. I haven't sorted them all out yet. Hope this helps.
