WILLIS from Charleton, Garsdon and Lea, Wilts. England

My WILLIS family originated in the 1700s in the Charleton near Malmsbury area of Wiltshire. One of the grandsons, William, married a gal from Berks and they moved to IOW about the 1860s. Seven children were born there, four of whom survived. These folur and their parents came to Canada in 1875 and settled eventually on the Manitoulin Island. From there the family has multiplied and branched to various parts of Canada and the USA.
I am still searching for more info in England of the siblings and ancestors of William.
