Kate Rosina Lovelock was born in Bermondsey in London on 30 October 1876, the daughter of Edward Lovelock and Charlotte Eliza Widdeson. Alas, Charlotte died in 1880 and on 27 November 1881 Edward married Amelia Jane Alley. Edward was a Book Binder by trade and probably in steady employment, but that did not stop he and Amelia from sending Kate to work at some point prior to the 1891 Census, when she, Kate, was recorded as an Apprentice in the Feather Trade.

Kate stuck to her trade, and in 1901 was recorded as an Ostrich Feather Cleaner. Moving up the hierarchy, by 1911 she had been appointed as an Ostrich Feather Curler, so far as our records go the only Lovelock so employed.

The City of London has a Web Site with a wealth of fascinating information, including some quite extensive data on the Ostrich Feather Trade:

From this we learn that the Curlers were the highest paid workers, so Kate was presumably relatively comfortably off.

But that Census reference to Kate in 1911 must have been right at the end of her feathery career, for at some point before the end of June she married Albert Beck, and by the end of the year their son Albert Charles had arrived. Although Albert Charles died in 1917 four other children arrived in 1913, 1915, 1918 and 1921 so that there was no question of Kate returning to her previous kind of employment.

In any case, as the City of London Web Site explains, there had been a serious down-turn in the trade because of the First World War, although there was also a resurgence of interest in ostrich feathers as a fashion item in the 1920s. There is also a suggestion that there might still be a modest present-day demand by burlesque fan-dancers!

That revival after the War was no doubt why Ivy and Eileen Lovelock had found employment in the trade by the time of the 1921 Census. Whilst Eileen was recorded as an Apprentice in the Feather Trade, Ivy's job was much more specific: Beater out in Ostrich Feather Manufacture. Just how long they stayed in the trade we cannot say - Ivy married in 1930 and was engaged on Unpaid Domestic Duties by 1939, whilst by then Eileen had become a hospital nurse.

There is more information than you probably ever wanted to know about ostrich feathers here, including how to harvest them yourself (first farm your ostrich as Mrs Beeton might have written!) :
