I am trying to find more about my 3x grandfather's sister Margaret, but have been unable to spot her on the 1881 census. I wonder if anyone can help? She was born Margaret WATSON in about 1834 and married John KNIGHT at Gateshead Fell on June 9 1866. Her parents Edward and Isabella WATSON lived in Sludge Row, somewhere near Chester le Street. Edward died at Sludge Row and he was buried at Chester le Street on January 26th 1835. (I don't know where Sludge Row is!) I have birth marriage and death certificates to verify that I am following the right person - but somehow she just seems to have disappeared in 1881 She should be listed as Margaret KNIGHT aged about 46 and she should have a son Edward WATSON aged about 19. I cannot find either of them, together or separately. I have census records of Margaret as follows: 1851 CENSUS of Gateshead HO 107/2402 folio 604 13 56 South Ships Cote Daniel Robson, head, married, age 37, joiner Jane, wife, married, age 34 Jane, daughter, age 4 Martha, daughter, age 2 (all above born DUR, Gateshead) _Margaret WATSON, age 16 house servant, born DUR, Chester-le-Street_ Gateshead 1861 CENSUS RG 9 3805 76 5 30 Low Fell, Durham Road East Side Isabella WATSON head W 57 laundress Wylam, NBL _Margaret WATSON dau U 26 laundress Pelton, DUR_ Isabella PUNSHON gdau 8 Netherton, NBL Thomas G PUNSHON gson 3 Gateshead Fell, DUR MARRIED June 18 1866 to John William Knight at Gateshead Fell John Knight died 29 November 1867 in Gateshead Workhouse 1871 CENSUS RG 10 Piece 5062 folio 13 page 19 Gateshead, Sheriff Hill Union Place west side _Margaret Knight widow 34 ag labourer b Pelton Fell, DUR_ Edward Watson son 9 b Low Fell, DUR 1881 Census - NOT FOUND 1891 CENSUS 1 Union Lane, Gateshead RG 12 4185 64 27 _Margaret KNIGHT widow aged 55 charwoman_ boarding with Ann Lennox head widow aged 56 also a charwoman 1901 CENSUS RG 13 4760 67 66 440 Woodlands Gateshead St John's parish _Margaret KNIGHT aged 65 servant_ to an oil merchant Ralph Thompson and his wife Maud Mary Thompson Margaret died in the Dec Quarter of 1909 aged 74.
