Sorry I missed yesterday's update. I had a blood sugar issue.
I sort of shifted gears after exhausting sources on Malcolm MacCallum, by turning to allied families. MacCallum/Callum kids married into several local Salem & Lynn families. Ann Callum, for example, married into the Twiss family. Her children married into the Nurse, Very and even Callum families.
I was able to find some new data on the Twiss, Nurse & Very clans. Not a bad day.
