Unfortunately I don't know anything about the house. I only have the reference of the southeast corner of Arch and Oxford from her estate papers. No address was given. I also have a deed indicating Mary Knox bought property in Alliance, Lot. No. 186, in February 1873. There was no mention of streets but perhaps they weren't named yet. Do you think the brown house that is there could date back that far? I'm thinking a house that old might have been torn down by now. I would like to see a picture of it if it's not too much trouble. Thank you. Kathy
