My greatgrandfather was Mike Cox of Tippah County. He died in 1910 and was the oldest man in the county at 114 years old. He married Martha Geno Crawford in 1863. Mike Cox is mentioned in the Tippah County Heritage Book Volume 2. Does anyone know when and how he immigrated to the US from Ireland? The heritage book mentions he took a sailing packet from England but gives no other details on the dates or port of entry. Any information would be appreciated.
