I came across this doing a search. Sorry to bring up such and old post. But....
Mike Brennen and Amelia McClanahan are my great great grandmother and grandfather! They had a daughter (my great grandmother) Mary "Ellie" Brennan. I was able to gather some info on Amelia and Mary (they moved off to graves county, ky), but nothing on Mike. He must have died between 1886 and 1900. He was of Irish decent. If you have any other info on him please let me know.
