Hi both
There unfortunatley is no mention on the 1901 census of Lilian.
I've looked under any obvious mispelling etc (I've been doing family research for some years now, even tracing one side of the family back to 1500's ~ so am used to finding all sorts of strange spelling). Another thought is that she could have been adopted by another family and later reunited with her "real" family. Think I might just bite the bullet and order the birth cert.
Thanks for you thoughts, ver much appreciated
Margaret
