I acquired their death certificates and knew that John drowned at Lesbury in 1874 and Harriet died in Amble in 1893. They could not be buried with other Henderson relatives in Amble West Cemetery as that opened in 1905, but I still kept my eyes open to see if they might have been mentioned on a subsequent memorial there. The death dates made it possible for Harriet to be in Amble East Cemetery, but that opened a little too late for John. However, I still had a wander round the cemetery and checked an online list of burials. No luck there either. My next thought was Warkworth St. Lawrence’s Church. There were Hendersons there too, but not this couple.
Then finally the penny dropped. There was another cemetery in Warkworth too, on the road up to the beach. There they were, together with two of their boys: Henry Henderson (1846-1871) and Archibald Henderson (1836-1874) – so easy to find once I finally got myself into the right place. It must have been tough on Harriet as she lost her son Archibald only 4 months after losing her husband.
