Does anyone know anything further of this Herbert Newton JARRETT (also spelled JARRAT)?
His wife Maria was a daughter of Catherine LAROCHE and Charles BERNERS (m. 1765). Herbert & Maria JARRETT's known children are Herbert Newton JARRETT jr., 1797, Woolverstone, Suffolk, England; Alicia, 1801, Baconsthorpe, Norfolk, England; Wilfred Lawson, 1803, Baconsthorpe; Mary Ann, 1805, Baconsthorpe.
Maria's twin brother William and another brother Henry BERNERS also married JARRETT/ JARRAT women, two daughters of John JARRAT. I don't know if Herbert is also a child of John JARRAT, or if he is a cousin or some other relation to the two JARRAT girls.
The history of the LAROCHE / BERNERS family was found in a Google book from 1804, The New Baronetage of England. The children of Herbert and Maria were found using FamilySearch.org.
