There are three objects here but they are all connected. The first is a ledger from a shop in Carrickfergus, Northern Ireland, which dates back to 1868. One of the customers mentioned in the ledger is a Sergeant Milligan, who was stationed at the town's army garrison. Years later Sergeant Milligan's grandson - the comedian Spike Milligan - came to visit the town to trace his ancestors. He was unable to find any evidence of his grandfather's time in Carrickfergus. So, when I came across this book, I contacted Spike, who was delighted. He sent me a letter and a cheque to pay for the postage of the book to send to him. But because of circumstances the book never made it to him. I have kept both the ledger, the letter and the cheque - they are treasured artefacts that link Carrickfergus with a world famous comedian and writer.
