I am working to differentiate two people of the name Jacob Sommer who lived in Philadelphia county during the Revolution. The differentiator between the two individuals is mostly place - one lived in Germantown and the other lived in Moreland.
I recently discovered many original papers related to the Sommer family of Moreland, which I would like to use as evidence. The issue is that not all pieces of paper that have the name of Jacob Sommer also have the place name of Moreland. However, I believe all these papers relate to Sommer's of Moreland because of the history of how the documents were passed down. Jacob of Moreland had only one granddaughter to survive him down the line, and when she died without issue, all the Sommer family papers, which apparently had been saved and passed down to that point, went to the granddaughter's husband, and all his paper's somehow ended up in a museum collection in Wilmington where I found them.
I believe that the fact the documents were passed down the known family line of Jacob-Moreland is evidence that those documents were once his, even if the content of each document does not identify him as being of Moreland. Am I correct to be thinking this way? And if so, how do I cite the custodial history of the document as evidence?
thanks for any help,
