I am looking for an explanation of the relationship between the Trott, Cambridge, & Tamplett families of Charleston, SC.

My ggggrandmother was known in family records & other records as Julia Cambridge (1828-1890; however, her marriage announcement was for Julia C. Trott. There was also a lawsuit brought on behalf of Julia C. Trott & other members of the Trott, Cambridge & Tamplett families. Names in these families include Tobias Cambridge, Tobias Cambridge Trott, & Tobias Peter Tamplett Cambridge. Some census lists show members of the Trott & Cambridge families living together or in close proximity. It would seem likely that there must have been a marriage between these families at some time, but I haven't been able to uncover it.

Thanks for any help someone can provide.
