I believe that Elizabeth's husband was Samuel, born bet. 1780-1790 and died in Jasper County, Georgia.
On the 1830 Jasper County census (with Samuel Boyd as head of family), there is a child listed as Deaf/Dumb under the age 14.
On the 1850 Pike County, Georgia, census (with Elizabeth LKU as head of family), her son Samuel is listed as "idiotic."
In the book "Abstracts of Deed Book A, Spalding County" there is the following record (with Elizabeth's son Jonas as Admin) :
Abstracts of Deed Book A
State of Georgia
City of Spalding
June 16, 1853
Jonas Boyd, said State and City, Admin of Samuel Boyd of Jasper Co., deceased, at public sale to Lucius Wagner, highest bidder, said State and City. $1135.00. Land in Spalding County, 3rd District, #113. Acres 202½.
Jonas Boyd, Admin. of Samuel Boyd, deceased
Witnesses: John T. Walker, J.B. Beall, JSC
Rec: January 19, 1854
Henry B. Holliday, Clerk.
There may be a will for Samuel Boyd in Jasper County.
Note: Spalding County didn't exist until 1851 and part of Pike was taken to form it. That's why this family was in Pike for the 1850 census year.
