I seek descendants of my great-uncle, James Griffiths, and his wife Margaret, born respectively in 1851 and 1853, Welsh immigrants; James worked as an engineer at Leadville before coming to Boulder in the early 1880s. Their daughters Elizabeth and Margaret married at Boulder in the early 1900s, Elizabeth to a Yockey, Margaret to a Burch (I have more details). James and the two Margarets are buried in the Columbia Cenetery, Boulder. Can anyone tell me more about this family. Have I any cousins willing to talk to me? Lois (in Canberra, Australia)
