A new offering this morning from Ancestry.co.uk is the London Electoral Rolls 1835 – 1965 so quite a wide range of years. The rolls generally give you a name & address, which is so helpful for those between census years.
There is a good explanation of the rolls on the site …..
Electoral registers are lists of individuals who are eligible to vote during the time the register is in force (usually one year). Registration for voters in England has been required since 1832, and registers were typically published annually, though some years had two. Registers were not published during the latter years of World War 1 (1916–1917) or World War 2 (1940–1944).
Restrictive property requirements denied the vote to much of the population for years, though these were eased somewhat in 1867 and 1884 through the Second and Third Reform Acts. They were finally removed, for men, in 1918, when most males age 21 and older were allowed to vote. The franchise was extended to some women over the age of 30 in 1918, but it was not until 1928 that the voting age was made 21 for both men and women.
Thus, the number of names listed in the registers increases with the expansion of suffrage in England, and the 2 million images in this database list more than 100 million names.
