Well done Suz.
I have just done another 1911 index search, using Charles Moon and looking for other members in Eastbourne and get the following, all in institutions:
Charles b. 1847
Elizabeth b. 1873
Ruby b. 1899
Rose b. 1904
Winifred b. 1907
Unfortunately, it's not possible to confirm who is family.
Going back to your earlier post Suz, the only Ruth I can find of about the right age, is a Ruth Emily, born Sept Qu. 1898, East Grinstead. Ruby is drawing a blank.
