Elizabeth Motsinger was the daughter of Jacob Motsinger(1799-1847) and Martha Idol(1795-?). Elizabeth was born 1838 in Davidson County, NC. Jacob Motsinger migrated to Johnson County, Missouri during the mid 1840s with alot of the Davidson County families.
Abraham Motsinger Robertson was born 1824 in Davidson County, NC. I do not have his parents yet. Elizabeth and Abraham married December 30, 1857 in Johnson County, Missouri. The children you have listed are the same as mine.
I am currently working on a William Robeson(1770-1842) who may have been an uncle to Abraham. He lived in the same area and the surname Robertson was changed from Roberson. I have alot of info on the Motsinger line. Just let me know if I can help.
