Nightingale/Simpson/Fallis search

I am looking for data on Nightingale family members in the Cambrige, England area or with origins in that area. Current verifiable direct line data for my husband's family goes back to Joseph, yeoman of Barton (d 16/12/1782)
I am also interested in Simpsons in the Aberdeen, Scotland area (My great grandfather John left the area in 1920s with his family (children Helen and George) returning with his second wife Betty who died in 1970s at Mintlaw.)
I am also interested in the Fallis family of Sark and (20th century) N.Ireland.
I have few facts about either family, both of which were working class.

Any information would be appreciated.I would be willing to share any data collated, but at present that is very little.
