Yes, Anna is my older (half) sister by my mum's first husband. Katherine married again (in 1948 I think) and had my brother (Edward) and me (Sarah - called Sally). I know that her brother and father (Elfed and David Vane?) lived in New Zealand and that she lost her brother at a fairly young age (I remember her receiving the news when I was quite young). I've only just started doing this, so have very little information. Anything you can tell me would be good to know. And how are we related??!!
