Wedded Blake sister

The wedded Blake sister has appeared only in a flashback showing her wedding photograph being taken. She was married in what looks like a space-suit. Her sister Daphne wasn't able to fit into the "bridal air-lock" because she had swollen up so much from eating shellfish.

It is possible that this sister is Daisy, Dawn, Dorothy, or Delilah. If not, this may be an as-yet-unnamed astronaut sister.
