adding a family to the tree.

My great, great grandfather, Pinkus Hartman (Hartmann) and great great grandmother, Genendel Segenfrind are listed in JRI Poland as married and having three children, one of whom is my great grandmother, in Borek Szlachecki, which is in the Krackow district. Should I add them as part of the Krackow project or is it just for inside Krackow? My great grandparents were also married there and had three children there, one of whom is my grandmother. I don't have all the JRI Poland records, just the generation before them.
