Hi Donna,
On FREEBMD I found a marriage for a Thomas Rhodes & Polly Wilby 1905 June 1/4 N. Brierley 9b 360.
There are births registered for N. Brierly & Chesterfield from 1911-1918.
It may be you'll have to send for your Grandad's birth cert. if you don't have it for your Grandmother's name - then send for the marriage cert. of your G. Grandparents.
This may or May not be your family Did your grandad have a brother named Harry?
