Hi David, I am not related to the Allen family directly, but have been researching them because some of my aunts, uncles, gr.aunts and gr. uncles have married into the family. There are a lot of Allens listed at this website.
When you get the grid of states, click on AR and then on 1860 INDIAN LANDS ARK.TERR.FED. CENSUSThere are quite a fewof Allens there,who were married to *NATIVES* and I saw several mulatto women listed with a partner Allen. Try every resource and we will all be cheering for you. Incidently, I am trying to find a connection with these names; STORY, WHISENANT, GRIFFIN.Plus several more, that I have forgotten with out the records on the table.
