Wes, At www.rootsweb.com/~msbenton/cemm.htm Archibald and several of his family are listed with birth and death dates and where buried.
They also are listed in a family group on the LDS site (search word:McKee, look for Archibald)
On 11-12-2000 I printed out a Rootsweb World Connect Project site titled, "Tippah Co Miss Connecting Familys".The contact on the site was firstname.lastname@example.org.Don't know if the email address is still good or not.A lot of Archibald's family up until the current time are there. I think how I got there was rootsweb home page, click on World Connect Project, proceed to search for McKee on submitted family trees and look for Tippah Co Miss Connecting Familys on hits.
I have tried for some time to connect my Hardeman Co TN McKee's with Archibald and believe there is a connection. One of Archibald's sons (Charles) married Molly Ferguson at Hardeman Co.(and I think Charles and Molly lived in Hardeman Co).In 1840 on the Tippah Co MS Census listing William McKee as one of two males 30/40 years old I think Archibald was the other male but don't have hard facts to base that thought on.There is evidence of an Archibald McKee in Mississippi as early as 1826-1827 at the Jackson Land Office and from 1829 thru 1837 at the Mt. Salus Land Office.This earlier reference was not Archibald born 1812 in SC as he would only have been 14 years old in 1826.On 1829-04-01 both Archibald and William McKee were listed on the Mt. Salus land records.On 1832-02-01 both Archibald and a Robert McKee were listed on the land records.A Samuel McKee was on the Mt. Salus land record on 1840-02-10.
I haven't connected these MS McKees with Hardeman Co TN yet.Perhaps you'll make connections on your part.Good Luck.
