I am of the line of Roger Mowry and Mary Johnson, which then goes to James Phillips (of Michael and Barbara) and Mary Mowry. The grandmother of Mary Johnson is said to be Hannah Throckmorton. I am looking for more info on her line.She married John Johnson. It is said Hannah is of Sir William Throckmorton, but the dates do not match. She born about 1570. The Michael Phillips (b.1630 Newport) line remainded in Providence RI for 200 years. The Trockmortons are well documented.But where is Hannah?
