The Tryon Family has a significant presence in Pennsylvania -- Philly, Pittsburgh, also the founding of Tryonville. For my own line, I am pretty confident that the Tryons I find in the Scranton/Luzerne area in 1870, 1880 are my ancestors. I can't trace them much further and the evidence is limited to two census records and some directory records in Scranton. My Ansyl Tryon is reportedly born in Binghamton, NY (which is relatively close).
I am not sure the best way to cross-categorize between name and area studies. In the case of the Tryon surname I created at the top level the broadest category: Tryon Name Study and two very broad regional categories under that: Tryon Family in America and Tryon Family in England. The Tryon Name Study catches any I don't yet know how/where to categorize geographically a set small enough it didnt warrant a regional subdivision yet. Perhaps the next phase is to subdivide the Tryon Family in America by subregions?
If anyone is knowledgeable about Scranton, South Abington/Luzerne County genealogical resources between 1865-1890 I would appreciate guidance or assistance.
