I don't know if there is any connection but I have a Nicholas Mattice who was born in Cornwall on March 25, 1793.He married Raechel Wastman one of their sons was Reuben Mattice Born in Weston, Ont. on May 23, 1823. Nichol;as's father was William Mattice born in Schoharie, N.Y. He moved to Canada in 1783 because he was a loyalist and had his property confiscated. I hope this can be of some use to you.
