Hi,
Made it to Chesterfield today, - sorry I can't find him on the registers for Spital Cem. Boythorpe didn't open till 1919, have you managed to find him on the 1871 census, a Chesterfield address may help a bit. Staveley and Brimington cems also open in relevant times I'll keep him in my book, you never know where and when these people will turn up!
