Unknown deguerretype #1 - Two Men

I'm Sean Ryan McDermott. I was born September 18, 1974, in Cincinnati, Ohio - Where I also presently reside. I am the only child of George Spencer McDermott and Sharon Lee McDermott (nee Bloomhorst). I have taken an active interest in researching my family history, and I am on a quest to trace back my paternal lineage to as earliest as I possibly can. My home resources (other than the internet) are reasonably extensive in the form of carried-down family knowledge and data kept by my immediate and semi-distant relatives and ancestors. I have discovered an extensive amount of photographs of family members, on my fathers side of my family Most of the older information, which I've located, here at my home was among my grandparent's - (Arthur & Mary McDermott's) property which my father-George Spencer McDermott inherited, (both are now deceased) after the death of his mother and my grandmother, Mary Isabel McDermott (nee Heilman), in 1989.
