The Dwain W. Harris Lineage from Charleston, SC

I am currently researching information about my Great Grandfather JOE HARRIS who lived near Ballybay, County Monaghan, Ireland during the late 1800's. His wife was Mary Clarke and they had five children: George Clarke Harris born 24 May 1884 died 26 August 1967; Annabella Harris Jebb birth UNK died April 1973; John Harris birth UNK died October 1965; Elizabeth Harris Niblock birth & death UNK; Willie Harris born May 1889 died 14 November 1961. I am also looking for any information concerning HENRY WARTER or CATHERINE WALTZ who emigrated from Germany during the mid to late 1800's.
