I too am looking for Calvin Williams parents. I believe he may be a brother to Joel Williams.
Calvin is in Wood County WVA in 1850:
Family # 1:
Husband: Calvin P. Williams* age 43 born about 1807 Ohio Wife: Matilda (Shoop) Williams age 42 born about 1808 Pennsylvania Son: John P. Williams age 23 born about 1827 Ohio Son: Calvin Williams (Jr.) age 19 born about 1831 Ohio Daughter: Margaret Williams age 16 born about 1834 Ohio Daughter: Nancy Williams# age 14 born about 1836 Ohio Daughter: Mary A. Williams age 12 born about 1838 Ohio Daughter: Matilda Williams age 8 born about 1842 Ohio Son: Thomas Williams age 7 born about 1843 Ohio Daughter: Marcella Williams age 5 born about 1845 Ohio Daughter: Sarah Williams age 3 born about 1847Virginia Son: Z. T. Williams (Zachary Taylor) age 1 born about 1849Virginia
*Calvin P. Williams is likely brother of Joel Williams who married Mary Ann. It is said that he was a stone cutter/setter and worked building a county road through Guernsey County, Ohio, which is where most of his children were born. Calvin P. is not in the 1860 US Census of Wood County Virginia. His son is head of household in the 1860 census. He may be the Calvin Williams enumerated with Joseph and Susannah (Williams) Lawson, daughter of Joel Williams, below
Wirt County WVA Zackville Post Office:
Page 8 June 1860 Dwelling # 55 Family #55
Joseph Lawson age 40 male, white Farmer born 1820 Virginia Real estate value $200. Personal estate value $60. Cannot read or write. (According to the family he was a farmer and horse and cattle trader.)
Susanna A. Lawson3 age 25 female, white born 1835 Virginia
Calvin Williams4 age 5 male, white born 1855 Virginia
Martha Lawson age 2 female, white born 1858 Virginia
Benjamin F. Williams age 8 months male, white born 1859 Virginia
3 Susanna A. Lawson is Susannah Williams, daughter of Joel and Mary Ann (Mareyan is mistranscribed as 'Waregan'; the Mareyan spelling is also used in Joel Williams property assessment after he died.) Williams. 4This Calvin may be the son of Abraham and Mary Williams of Wardensville, Hardy County, VA in 1860 as a Calvin Williams of the same age and birth year is also listed with them. He is not Susanna A. Lawson's (Susannah Williams) son according to descendants of Susannah. *** Some say this is a mistake and the Calvin Williams is 54 years old (born about 1805) which would make him the Calvin Williams, Sr. in the above family. It is known that Joseph Lawson and Calvin Williams both worked as stone masons on the highway that went through Guernsey County Ohio.
# Nancy marries to John Wellspring, child William Wellspring whose son is Howard Wellspring.
Other Williams in the same district: Family # 2:
Husband: Joseph Williams* age 42 born about 1808 Virginia Wife: Judy Williams age 43 born about 1807 Virginia Daughter: Narcissus Williams+ age 13 born about 1837 Virginia Daughter: Martha Williams+ age 13 born about 1837 Virginia Daughter: Mary Williams age 10 born about 1840 Virginia Daughter: Cynthia Williams age 8 born about 1842 Virginia Daughter: Judy Williams age 6 born about 1844 Virginia Son: Thomas Williams age 3 born about 1847 Virginia Son: Joseph Williams age 1/12 born about 1850 Virginia
* Joseph does not appear in the 1860 US Census in Wood County VA. We assume he is also away or dead in 1860. + Here Narcissa and Martha appear to be twins, in the 1860 US Census in Wood County VA Martha is 25, but listed below Narcissa who is 22, other ages seem to be only one year different from this census.
Family # 3:
Husband: Nathaniel Williams age 63 born about 1787 Virginia Wife: Polly Williams age 52 born about 1798 Virginia Son: James Williams age 29 born about 1821 Virginia Son: Benjamin Williams age 21 born about 1829 Virginia Daughter: Margaret Williams age 17 born about 1833 Virginia
Family # 4:
Husband: James U. Williams* age 29 born about 1821 Virginia Wife: Rachel Williams? age 26 born about 1824 Ohio Other: Jenkins Stewart age 36 born about 1814
* Same as James listed with Nathaniel and Polly? ? Could Rachel be the daughter of Calvin and Matilda?
Family # 5:
Husband: Charles Williams* age 23 born about 1827 Virginia Wife: Nancy Williams age 19 born about 1831 Virginia
* Could Charles be the son of Nathaniel and Polly?
