there was a Sarah Ann Wirt who married a John T Bayard or similar spelling in Maryland in l82_?. Age is barely right to be a second marriage to Oldham but I dont give it much. This info came from CD 208 of Broderbund and is undocumented although it is a quote of some records and a reprint with search capability. There are huge numbers of oldhams going back forever. All of mine are pre l800. Charles Severs
