Hi, I have discovered a Martha Broffan of Dawley, Shropshire who is my 6th Great grandmother. She married Thomas Garbett of Shropshire and had issue. I saw this question when I created Martha in my Wikitree family tree. I can't offer much else about her as I don't have many records other than the marriage record. Linking your Broffan's to my Broffan may be a difficult task but it may be the connection is very ancient and hence not easily traceable without many hours of digging. Best of luck.
