Biographical Notes

She was a daughter of Kedar (#1639) and Pegg (#1640). Census data confirms elements of J.W. Case's biographical information. She was working as a servant in the Samuel W. Young's household in Southold in 1850 (under the surname Albertson). In 1860, she was living with her sisters Eunice and Margaret in Greenport (using the surname Derby). In 1865 (NYS census), she was enumerated as Tura Derbey, living with her sisters Phillis and Margret. And in the 1870 Federal census, she was living with her sister Margaret (surname recorded as Darby).

According to court papers, Keturah wrote a will on July 28, 1870 which wasn’t probated until the death of her sister Margaret in 1879. Legal notices placed in the Sag Harbor Express in 1879, suggest that Keturah’s primary beneficiary of her 1870 will was her sister Margaret. When Margaret died in 1879, both wills were probated on the same day. Keturah’s secondary beneficiaries were identical to Margaret’s primary beneficiaries—children and grandchildren of their deceased siblings.
