Hi, that's an interesting query, I'm researching the lines of my husbands families and note that they also came to the iIsland from the UK, some coming from the South coast. I know that there's was a lot of building work going on during that time in St. Helier (the Westaway family were big in the building industry then) as I live in the Island I will see what I can find out for you.
Best regards
Sandra
