I have some Henry's in my Boice/Boyce line but looks like you are the Dutch line of Boyce's and I am of the Irish so probably could not help!
But I am interested in why the name was changed from Boice to Boyce.as some of my family is Boice and some Boyce. Its best to eamil me normalee2@wcoil.com,as I don't look here often
