Also a possible son to the couple. Horace's middle name was Victor and there's a birth registered in Bodmin in 1938 of a Victor W Jago mmn Harrison but sadly a burial 2 Aug 1838 in Bodmin of Victor Wymon Jago aged 1 month.
Horace Jago was from Bodmin as well. Perhaps there was an assumption that her surname was the same as her mother's somewhere along the way.
