Until recently when a mother remarried her other children took the new husband’s surname. Two
examples in my family were Harry Mitchell born 1905, became Harry Napier from 1913. And Jim
McQueen also born 1905 became Jim Campbell from 1914.
In another case, Charlie Hale became Charlie Hughes, aged four in the 1881 census when his mother
remarried. His father was Richard Hale.
And this same Richard Hale aged 19 in 1861 census was found living with his Uncle John Robert Hale. In 1851 he,
Richard was with the same Uncle as eight year old Richard Westley.
Families in the larger cities at the time were prone to losing family members due to their not
understanding about hygiene, and overcrowding. Louis Pasteur’s discovering micro-organisms in
1870s eventually changed all that.
This also means that most of the time your family in the census is not going to look anything like it
does on the Family Group sheet.
HINT: A run or sequence of census [or directories or voting rolls/registers] is always worthwhile. e.g. 1851, 1861, 1871 etc
For other combinations of a family I refer you to the chart About Family under FAMILY 2.6
