In '71 martin was 56 amd so if that is right he should be recorded as 66 in 61 but the one craft found is recorded as 64. Mary should have been 66 but it shows this mary as 65. mary could have been 66 the day after the census return was taken!!! We don;t know who gave the information on the form the enumerayor collected, it might noy have been martin it could have been mary and she could have got his age wrong!!! the ages on all cenesus returns can never be considered accurate as we do not know who filled the form in, the enumerator could have even misheard the age if he had to fill the form in for them, many could not write, the enumerator could have even transferred the info from the form to his enumerators book in error as he maybe misread someone else's numbers!!! This family do seem a very close match, it would also be unusual for a family man in his 60s to emigrate, unless he was going with his adult children. he would have had to support himself for his passage and job when he got to america, and what about mary? She would be elderly to be undertaking a journey like that so late in life, unless they did indeed travel with one of their sons or daughters.
