I wonder if someone could find these people for me please.
I have this family in the 1871 Census, Leyton, Leytonstone. I cannot find him in the 1861 or suprisingly the 1881 Census!!

Alexander B Millington, aged 56, born Edgware, Middlesex. Occupation, Civil
service at the GPO Savings Bank. I know that he died in 1900.
There is no wife as she isn't on the 1871 Census and Alex is a widower
children
Ellen J, aged 30 b. Peckham, Surrey
Richard H, aged 29, b. Peckham, Surrey
Madaline E. aged 27, b. Peckham, Surrey
