Thank you, Mark. Interested as to why it was called the Suger House. Certainly no mention of sugar refining in Selby anywhere I've looked over the years, though of course no reason why not ... just an extension of the trade in Hull and Goole (but earlier !).
Seems, as you say, to be the name of the house/dwelling, which makes me wonder if there was a Walmesley connection to sugar that I've not found yet. Maybe good money was being made from an investment in a (London) refinery, or maybe there was a plantation connection perhaps through the Lancashire side of the family.
Can find nothing useful yet, but will keep looking.
Thank you.
