I couldn't find her death on Ancestry, most of Bawdens lived in Cornwall, England, but many lead miners came from Cornwall to work on IOM. There seemed to be a family without a Margaret in Patrick in 1941.
1841 Census, ?Ballaharron, German, district 3:
John Bawden, 35, lead miner, born England
Margaret Bawden, 31, "
John, 11 "
Mary, 8 "
Edward, 5 "
Benjamin, 3 "
Wm., 5 months, born IOM.
I hope this helps.
Janet.
