As newsletter editor for the Milam County Genealogical Society I published your query in our current newsletter. Here is the reply from one of our members:
"There is a query in the Jan/Feb newsletter that I would like to answer but the e-mail address is not complete. It is the second one relative to Spence. If you have a more complete address, could you let this person know that I.S. Spence is listed in the Milam County Cemetery Books on p. 95 in the section called Burials- Unknown Sites. The listing shows I.S. Spence Death R., Coal Mine died - 1912. Since she has his death certificate listing the precise date, I am wondering if it does not give the name of the doctor who signed it which may be a way of tracing to community.
Further, I would tell her that the funeral home was Henne & Meyer. They also operated a funeral home in Thorndale as my great-grandfather- Andrew Urban- bought them out in the 20s. His oldest son, John Urban, was the Thorndale undertaker while Henne & Meyer still owned it and, of course, continued after his father acquired the funeral home.
Since he died in a coal mine I would expect him to be buried in the vicinity of wherever that work was done in the early 1900s. Not sure if that would be in the vicinity of the ALCOA plant. I think miners in that era would live within walking distance of their work and there may have been a named community where coal mining was being conducted.
If you have her e-mail address, would you just forward this? Thanks. Pat Larsen."
Hope this helps in your search. Linda Whorton
