You list Martha Allen as a dau. of Thomas Allen and Elizabeth Summers.I am descended from this couple through their son, Thomas Jr.I do not have a Martha listed amongst the children of Thomas and Elizabeth.I have:
Thomas, b. 5 Mar 1820 David, b. bet. 1827-1828 Eliza, b. bet. 1828-1829
I also have listed a John Allen, b. 1811-1812, but I am not sure why I have him listed as a son.All of these were from the 1850 US census for Fountain Co., Indiana, although I also have Thomas, Jr., and David listed in the 1880 US census for Polk Co, Missouri and Benton Co., Arkansas, respectively.
I would appreciate whatever you have that can fill in the gaps.
