Hi Nell,
Yes, it is a curiosity. I have found what you have discovered. I've had a suggestion that Fanny married a William Emanuel Hollins. I've also heard from a chap who is the grandson of Fanny's neice. Unfortunately he doesn't know the married name of Fanny. he has two possibilities one of which is a fellow with the surname Wight.
I've sent off for fanny's birth certificate which should, I hope, shed some light.
Thanks for interest Nell.
regards,
Don
