I've just started delving into my family history. Have found one set of Great-great Grandparents and children on the 1881 Census and a couple of the children on the 1901 Census, but no trace of any of them on the 1891 Census.
A friend suggested that they may have been on holiday and therefore registered in a different part of the country, but they are not to be found anywhere.
The fact that my great-grandmother and one of her sisters are on the 1901 Census obviously means that there were, at least, two of them still alive in 1891.
Anyone got any ideas where to look next?
