I had the two baptisms, but after that Henry is consistently shown as younger than Hezekiah. I wondered if Hez had been one of twins, with Henry dying in infancy, and a subsequent son given his name. I suppose we'll never know.
It's fascinating that Hez didn't marry until he was 56, and then only because he "had to". When he went into the Charterhouse Clara was only 38 so would not have been able to go with him. And since they were together on the census 4 years earlier, how come he was given a room at all?
People's lives are always more complicated than we imagine. Thanks again for your help.
