The daughters of Joseph Sundvik... (Curse of Fenric pt. 4)
I recently made a post about my favourite occult- themed Who episode - The Curse of Fenric.
I forgot to mention one of the small, but cool tidbits contained in the episode...
Joseph Sundvik a resident of the fictional Yorkshire village of Maiden's Point died in 1872 and was buried in the local graveyard, he was survived by his daughters, Sarah, Jane, Martha and Clara.
Given this episode aired in '89 only one of those names referenced an existing companion, the others, as we know would come in time.
Pretty cool, eh?
