Isaac Mansfield was a joiner who built his home in Marblehead in 1721. He may be the same person as Capt. Isaac Mansfield (born 1695 and died 1760) [there was also an Isaac Mansfield, Esq., born in 1722, and another Capt. Isaac Mansfield, born in 1750]. The house was rebuilt in 1810 by housewrights John & Eben Harris. Built on Mechanic Street, which was then a cow path leading to Brimblecomb Hill, the house is now the Brimblecomb Hill Bed & Breakfast.
