I don't know if this helps because I don't have many dates but I have a Thomas Jarman (1824-1909),married to Anne Savaker (1832-1922), married 1863. Thomas Jarman was the son of Thomas Jarman and Mary Ann Morgan. The elder Thomas Jarman was the son of John Jarman of Llanfan, Brecorshire. Mary Ann Morgan was the daughter of Margaretta Theodocia Ingram who married George Morgan of Hendre, Radnorshire. My source keeps going but I'll stop here and ask if I've struck a bell?
