What is the mother country of the massachusetts bay colony

If Massachussets Bay Colony has a mother country, it would be England. Their first colony arrived from England and Barbados from 1630 to 1640. They were mostly Puritans so, the grew in large families and needed a lot of farm land. Before that, most of them were settlers of Cape Ann, a place northern Salem, for a time but when that investment broke, they organized their new settlements around Salem and Boston.

its main object was the establishment of "settlement houses" in poor urban areas, in which volunteer middle-class "settlement workers" would live, hoping to share knowledge and culture with, and alleviate the poverty of, their low-income neighbors.
