I believe that John (a farmer) died in Stradbroke 1847 and Jane in 1877.
1847 must have been a dramatic year for Jane as two of her 10 children also died in 1847!
In 1851 Jane was running a 200 acre farm assisted by 2 outdoor workers and 3 house servants and 5 other children still at home. Of the other 5 children 2 had died by 1851.
In 1871 Jane was living with her sons Thomas, John & Albert & daughter Martha.
In 1851 her eldest son, Henry was farming at Valley Farm, Denham Road, Stradbroke, with his wife Elizabeth (nee Larter ) plus children, one of whom was James FARROW Cracknell born August 1845, 3 months after the couple had married!
n.b "Farrow" may well be a surname linked to the Cracknell or Larter line?
All this info will have to be verified by you the reader!
