Research Goals for the Duncan Lineage: 

  • Add a generation behind William W Duncan.  Need more sources for his parents Hugh Duncan (1799-1870) and Rachel Glass (1808-1897).
  • Find more information on Jennie Salina Ford (obituary, death record)
  • Find more information on Margaret Rostrom (obituary, death record, parent’s records)
  • Order a copy of Andrew Jackson Duncan’s Civil War diary from the University of Michigan.
  • Find another Duncan descendant that has done a DNA test to compare with.

  1. Did William DUNCAN die 1906 or 1907? You have both dates.


    • Thanks for pointing that out. According to his death certificate, he died 31 May 1907. I haven’t updated this page in over a year and a half, so it’s probably time I go through it again.
      Are you related to these people? I have yet to connect with any Duncan distant cousins.


      • About 1828, my DUNCANs left County Londonderry, Ireland and emigrated to Frampton, Quebec. Eventually they spread down into the states. I’m broadening my search as I look for some strays.

        I found some of the Pittsburgh DUNCANs and a W. R. DUNLAP in the oil business to be interesting reading. It was the DUNLAP & DUNCAN name which Google directed me to your blog. Unfortunately, I see no connection of my DUNCANs to any of the Pittsburgh DUNCANs or your Ohio DUNCANs.

    I am a descendant of Hugh’s brother John (born 1809). This is a hugely frustrating family, as there should be more documentation than there is!
