According to notes I have from my grandmother (Vera McEwen, nee Weston):
Sarah Howard married George Tucker and had children Joseph and Phoebe.
George Washington Tucker was Joseph and Phoebe Howard's great-grandfather. He was the first settler in the Westmeath area and came from Augusta, Maine. He was a United Empire Loyalist and built on the Ottawa river. He later gave land for the first school. His daughter-in-law, Rachel Stone (spouse of Rex) was the first school teacher.
Westmeath was settled before Pembroke and the people of Pembroke came to church in Westmeath. Georege Tucker (son of Rex) was very prominent in the community church and school.
