My Mom Bonnie Tipton-Eggman forwarded me your posting.
I know much about our campbell line that went from scottland to ireland to virginia to KT to Mo. and then in 1845 left Mo. arriving in 1846 at Sutter Fort Calif.
Now one of the lines of this group ended up in Porterville California. One of the Daughters of David Campbell married a Webb. in Porterville. David's brother Ben started a town that is know as Campbell California. So if this is your Campbell/ Wedd line let me know and I can tell you more about this line and about the Webb cousin I met.
I "suspect" that some of my Campbell line were from Missouri, but cannot find out anything for sure as all I have to go by are the names of my ggrandparents. They were George Dallas Campbell m. Mary Webb. I believe that some of my WEBBS are also from MO. I had a great aunt named Dade--don't know if her maiden name was WEBB or CAMPBELL, but she lived around Caruthersville, MO. back in the 1950's and she was married to a William "Bill" Thompson/Thomson. If anyone can offer any info on any of these names it would be greatly appreciated.
