All Tyzacks in the world appear to have come from a group of glassmakers living in Lorraine before 1400. For two hundred years there the family exploited privileges as glassmakers, granted to them by the Dukes.

By 1600 they introduced Lorraine window glass into England.   During the early years they moved a lot. Then, for about one-hundred and twenty years, they anchored in Newcastle and Stourbridge.

Later some moved into other crafts such as edge tools. The reason for the switch from glass to tools was the depression in the broad glass industry about 1710.
