HI SHIRLEY - if he were in the military, you might check the Civil War lists - that would give the names, usually, of wives and sometimes children who made claims for a pension.I will try to look in my library - since we have the whole set of books --many volumes.I did find some of my relatives in those volumes.Yes, there are many "Hirams" but not so many born in Ohio, which is a good thing! and since we have the 1880 US Census which shows his wife and some of the children, that rather confirms things.Also use USGENWEB and check out NEBRASKA and OTOE COUNTY - or territory - I often write to libraries in the county and they are most helpful. Since all the kids were born in Nebraska maybe there are birth records that would show something about him.
As for his father "John W." - I don't think he was a Jonathan at all. And he may have been born in Ireland or in VT - My Allens came from "the west of England" to MASS and then on to CT to help found Windsor, CT, but then the kids moved to VT and WI and finally family to Iowa!And believe me "Samuel Allen" was VERY hard to trace!Never saw so many Samuels !!!
The fact that in the 1900 US Census he was living as a "boarder" with the Nich Ackerman family in Johnson Village, Nemaha, NE shows that he had abandoned his family for some reason - divorce or illness, etc.Then in the 1910 Census he is definitely "divorced" - which is a shame - with all those lovely children to enjoy!However, he had been in Jail for burglary in 1860 - so he didn't have a very good start.although that may have been a "false arrest" by someone out to get him!
He did seem to care for hismother - as she lived with him in the1865 Nebraska Census - or she cared for him - who knows!
Would be nice to find the grave of John W. Allen who died 1844 in Miami, LOGAN, Ohio - sometimes libraries have collections of cemetery records and in 1844 most counties had death certificates -
Because John W. Allen married a lady (Nancy Dillon) born in NY perhaps he immigrated from Ireland to NY City and met her there - but she had parents in Bedford, VA....interesting!
Good hunting to you - I won't be having time to pursue this further, but I imagine, if you are like me, this "hobby" will be consuming a lot of your time!
