Yes he was apparently.I know Constance may lander married George clarke and had 3 girls one of who was my nan jessica but how we are related to him i am not sure.There are many landers on the census and it is difficult to move forward.
We also lived at number 10 Arter street, before moving to the shop on the corner with my mom & dad (Tatlow family) which was 65 Sherbourne Road.We lived at no 10 Arter Street and Landers Spinning Factory was almost opposite at nos 5-7. The Electoral Registers for 1950 and 1955 do not have entries for 5-7 Arter Street. However the 1950 Electoral Register (qualifying date 20 Nov 1949) shows Alfred J Lander living next door to the factory at 9 Arter Street. Was he a relative of yours?
