Her first husband, Hon. Charles Maynard, was a colonel of the Blues. In his youth he was almost lynched in Spain for sneering at the matador and riding bare-back on the bull. He was temperamental and drank, both apparently contributing to his early death af fifty. 
Blanche was then thirty years old and the mother of two daughters. After a respectable period of widowhood she married the Earl of Rosslyn. It was said that on his part it was a love match underlined by sound financial consideration. After their marriage they spent most of their time at Easton Lodge, the Maynard family home in Essex. Blanche was not particularly good-looking or clever but she had a formidable personality and much ambition. 
Late in 1879 her eldest daughter, Frances "Daisy" Maynard was summoned to Windsor to be vetted as a possible wife for Prince Leopold but Daisy, knowning the Prince was not keen, turned him down and married Lord Brooke, heir of the Earl of Warwick. In 1905 Lady Rosslyn became a Roman Catholic. When she died on 8 December 1933, she was ninety-four.
