I believe you are referring to Robert Templeton II (1673 - ???) and Robert Templeton III (1704 - ???), respectively. The spouses and dates match with what I've been able to collect/find. Robert Templeton III was settled in Botetourt Co., Va and married to Agnes Wilson. Martin Templeton (1767 - 1855) was the son of Robert Templeton III and settled in Pittsylvania Co, Va. Martin was married to Nancy King. I've found that I am a decendent of their lineage. Hope this helps.
