This lady died in 1974 age 65.I think she might be the widow of John E Henderson who died in the Mount Slesse plane crash in 1956.She was known as Nan or Nancy,but most of her family who had that name were actually christened Agnes.
Her maiden name was Smart (or possibly Henderson,also her mothers maiden name)

I have no idea if she remarried after John died and of course marriage records for the late 50's and 60's are not available online.But 'our' lady did also have Crichton as a middle name.
