If your Alexander Fleming did die in 1952, he died too early to show up on SSDI.But, unless you are sure of his death year, you might want to look for an obituary for the one I gave you in previous response.Just to make sure he is not your Alexander.
Have you done any census research?I would check out the 1880 census when Raburn would be about 11 years old.That is the first census that asks birth place of the mother and father of everyone in the household.On there Martin Jr, should show where his mother Polly Trolinger was born.Be sure to watch for Mary Trolinger, too.You may already know Polly was a common nickname for Mary.
Be sure to fill in as much as you can on the more recent ancestors, before you go back up the tree. In that process you may "stumble" across some very good information.
I had an ancestor in PA who sold some property in the early 1800s and said he had the right to sell that property, as he had inherited it from the will of his father, Thomas Irwin.Up til then, I did not know the father of my Samuel Irwin.Yes, I "stumbled" on to that bit of info. (^_^)
I would check the Carter Co, OK GenWeb site, for any possible info on your family that lived in and around Healdton.Some GenWeb sites are putting their cemeteries online.If not on the county site, be sure to check the archived section of the OKGenWeb Project, too.Post your query, with those dates, on there.You never know who else may be working on the family and recognize them.
Raburn died a little too early for SSDI.Have you looked for an obit for him?OK didn't begin state wide vital records until 1908, but a few counties kept them as early as 1891, so you might check to see if anything was recorded for Raburn in the county of his death.
You might post a query on the Parker Co, TX GenWeb site, see if anyone recognizes Alexander Fleming.Alexander was a popular Scottish name.I have Flemings with many named Alexander.Then I have one named Alexander Fleming Walker (Fleming was his grandmother's maiden name).My Alec Walker was in Parker Co, TX at one time.As I remember, Parker Co, TX GenWeb site has quite a bit of info posted. Happy Hunting.
