Not sure if this is the correct forum to post this in apologies in advance if not.
I have recently started searching my other half's family as he wanted to know more about them only to hit a bit of a problem.

So i got back to Joseph Gooch born in Norwich Norfolk in 1861 so i start looking for census records and jackpot

i found 1911, 1901 and 1891 and from there things took the turn!
On the 1891 census he has his mother listed a Maria B Sutherland and two of his sisters (Annie M Gooch and Eliza A Gooch) at first i thought this was good until i tried to dig deeper Maria seems to have many children only 3 with the surname Gooch and 3+ with Sutherland, she has remained single all the time and none seem to have a father on their records.
I have managed to find Maria on the 1891, 1881, 1871, 1861, 1851 and 1841 census however Joseph only comes up on the 1891 with his mother not on the 61,71 and 81. (61 i thought may be to do with month of birth and census taking place) I can't seem to find him.
I'm not sure where i have gone wrong or what to do to get past this.

Anyone had similar experience or any advice (apart from run away) it would be very much appreciated.
Have a great day.
Laura.
