BENCH George Rugby 6d 965
BOOTH Fanny Rugby 6d 965
The website will tell you how to order the certificate - (cost about 9.25 bp)
You will need this as there are many Fanny BOOTHs born in the preceding years and it would be helful to have her father's name and her age to narrow it down - but there is one born in the Rugby area in 1884.
I have looked on the 1911 census and she was born in Cosford in Warwickshire abt 1884 and Cosford is in the Rugby Registration District.
