Since posting the below topic the 1911 census has become available online. Sadly there is absolutely no sign so far of my great grandmother Sarah Fogden. What I know about her is posted below for anybody who is interested.
If you have any memory or any relation who might have been in any kind of relationship with Sarah I would dearly love to hear from you. I know it's a long, long time ago but if she married, which would appear the likeliest reason for us not being able to trace her, and had other children there might just be a chance somebody alive today has some knowledge of what became of her.
My first post on this topic read:
This is my first ever post, having discovered this site only yesterday.
I am desperately trying to trace what became of my great grandmother, Sarah Fogden, daughter of George and Caroline Fogden (nee Rastall). I have no knowledge of what happened to her after the 1901 census when she worked as a domestic servant for a clergyman Henry W. Bates and his wife Eleonor and lived in at 36, Buckley Road, Kilburn. Also at that address at that time was Frederick T. H. Turner (fishmonger, aged 38, brother of Eleonor) and Harriet Stowe (or Stone) aged 63, descibed as aunt.
Sarah, who was unmarried, had two children - Elsie Butler Fogden, born July 24, 1892, and Frederick Henry Fogden, born September 11, 1899 - who were brought up by her mother Caroline. Sarah became estranged from her family and any information, no matter how small or seemingly insignificant, would be very gratefully received. I have no idea whether she ever married or when she died - perhaps she even emigrated. I just don't know.
If anybody in your family knew Sarah or where she might have lived after 1901 or if they knew any of Sarah's brothers or sister - George Jnr, Ellen, William, Thomas or Henry - I be extremely grateful if you could let me know.
