I am searching for the origins of a Jules Martial Wys who appears to have arrived in London in the early 1860s with his French wife, Martine Garcia.

I'd be grateful for any information on this family. Is the surname Wys rare ? The only Wys family member mentioned in the IGI for Belgium is a Victoire Wys who was born in 1805 in Neerheylissm, Brabant, hence my post here.
