There were 2 Samuel Coddings who were cousins who married sisters. Good grief! According to past DAR applications, parents of my Cobb Codding were Samuel Codding and Mercy Cobb. Another researcher who has a website I will share, places Cobb as the son of Samuel and Mary (Cobb). I have not yet done further research, although I do plan that soon. So, these men were sons of brothers, still in the same line anyway. Try this website:http://www.familytreemaker.com/users/c/o/d/Mark-Louis-Coddin...
Go to Gen 4, #15, Samuel Codding.
Samuel's parents are either George Codding and Elizabeth Luscombe (I think!) or George's brother James.
PS--check out the whole website and let me know what you think.
