Wife of Harvey Boyd Duncan (1796-1861). Daughter of Thomas Laughlin (who was a Revolutionary War patriot) and Elizabeth (Duncan) Laughlin. Eliza's children included: Henrietta Josephine, John Dekalb, Thomas Paveril, Green Perry, Gwenn B., Joseph A., Mary Elizabeth, Sophia Narcissa and Harvey Montgomery Duncan.
Note: There has been some confusion as to which cemetery Harvey Boyd Duncan and his wife Eliza (Laughlin) Duncan are at. Inevitally, they were both buried at Evergreen Cemetery in Lineville, Iowa. This information provided by a family member and Findagrave member, Manxcat, should help to explain:
He [Harvey Duncan] was buried first in the Duncan family burying ground, one and one-fourth miles northeast of Lineville, on the farm of his son John. Here the body lay until about 1890 when the remains were exhumed and transferred to the Evergreen Cemetery in Lineville where they were interred beside the grave of his wife. The plain, old-fashioned slab-type marker that had marked his grave in the Duncan burying ground was re-erected until June 25, 1939, about a half-century later. At that time several collateral relatives of Duncan, including the writer (Wilma West?), transferred the marker from its place of storage and erected it to mark their kinsman's grave, erecting in accordance with directions furnished by Mr. Sammuel Vandel and Duncan's granddaughters, Mrs. Josie Duncan Judd and Mrs. Ellen Duncan Cravens. (The grave marker on the farm originally owned by Harvey Boyd Duncan was discovered by Mr. Samuel Vandel. Those who aided in erecting the stone were Mr. Harvey G. Duncan and Mr. Henry G. Duncan.)
