When Anne Lister, ‘Gentleman Jack,’ and her infamous diaries hit the headlines a few years ago, their popularity spawned a plethora of Gentleman Jack blogs, research and books which have focused primarily on Anne Lister’s romantic relationships with (a huge) number of women, but whilst they are an integral part of the Lister story, there is another woman lurking in the pages of her diaries: The original Lister Sister, Marian.

Marian Lister was Anne’s younger sister and the two women had a complex and fascinating relationship. The evidence reveals Marian to be a complicated woman who both resented, loved and was fiercely protective of her older sister. Forced to live together for a large part of their lives Anne vehemently disapproved of Marian’s desire to escape in order to marry a “carpet maker” feeling him to be unworthy of the sister she herself derided. Marian, for her part, did not understand her elder sister's relationships with women, but she accepted them, defended her and worried about her excessively even whilst she ranted about Anne’s spending, scheming and selfishness.

When together, the two women bickered constantly with Marian, literally at times screaming in frustration at her headstrong sister. Anne, for her part, complained that Marian was “simple … good for nothing,” yet her approval meant a good deal to her.

Here, for the first time, we look at the complex relationship between the two women, how it developed, its moments of triumph and tragedy, as well as the profound influence it had on each of their lives.
