I must apologise first of all for not checking all my sources and contacts on Genes Reunited,before I posted my first reply.
I checked later,and seen that someone whose Family Tree I have access to,lists this Penninah to have been born in c 1884 in Staffordshire.However she lists the Marriage to Samuel Nevitt,only as she appears to be related to the Nevitt Family.
If I was being wildly speculative,I would say she was the daughter of David and Annie Bosson,as listed in the 1891 Census;RG12/2160/53/41.David is listed as Bossow,and Annie and the daughter are listed as Brundrett.This David Bosson is as equally elusive in the earlier Census years,and I can't see any sign of him in the 1901 Census.
