I have emailed Worcester and have received the below reply: -
"We have a marriage index of Worcestershire covering 1701 to 1837 ; there are about 30 Sparrow grooms and about 20 Sparrow brides.
We have a burial index of Worcestershire covering mid-1700s to early 1900s; there are 550,000 names of which 93 are Sparrow. There are concentrations of Sparrow burials in Church Lench and Redmarley.
You may also wish to consider name variants Sparry and Sparrey.
We can offer searches of these registers. The base cost is £4.00 per register for up to 3 hits. See
http://www.bmsgh.org/sea.html Malvern Family History society have a good selection of baptism indexes covering Worcestershire

http://www.worcestershire.gov.uk/info/2 ... d_researchBear in mind, however, that just because Mary Sparrow was married in Worcester it does not mean that she was born in Worcestershire.
I hope that this helps.
Regards."
It seems that the FHL numbers aren't much help and I'm reluctant to pay £4 for up to 3 hits, in case the system isn't reliable plus the fact she may not have been born in Worcester, etc and as I've been made redundant, I can't afford to throw away money so will have to give up on this family line.
