Guy Fawkes, whose death is celebrated on Bonfire Night (Nov 5th) was born in York, and was baptised in the church of St Michael Le Belfrey. On my visit there this morning, I found that the register showing the entry for Guy Fawkes' baptism is on display this week, on its final day today so I was lucky to get to see it just in time. I can't read the script at all, but his entry is on the left and is the third from the top, with two small black vertical lines just next to it. Guy Fawkes, son of Edward Fawkes. The entry is dated 16th April 1570.
This nice lady whose name I omitted to ask (although we established that she knows my mum!) has been a guardian of the register while it's been on display. It'll be out again in January, as part of a residents' week taking place.
