Dear Listers. I am posting this to the Tyrone list in the hope that someone can help a little. I know how really difficult this early stuff is. Jane Duff of "Duffmount" married John William Duncan on Tuesday 6th April 1799 either in Derry or Co Tyrone. They were Presbyterian. All children born somewhere in Derry, probably Magherafelt or Belfast. William Duff Duncan 26 Jan 1800 Maria b. 23 Feb 1801 d. 17 April 1804 Robert 4 Oct 1802 d 15 April 1804 Maria (another) b. 9 March 1805 Eliza b. 22 Sept 1807 Above from Duncan family Bible printed in Edinburgh. Father, John William Duncan b. 1777 became a member of Lodge 777 of the Freemasons in 1808 which was then meeting in Magherafelt. ( I have his Mason's membership, and received the above information from the Grand Lodge in Dublin many years ago.) Mr. Duncan died in New Orleans Lousisana Territory USA in 1811. His family appears in Pittsburgh PA USA by 1820 (can't find them earlier) where they appeared to live very well and were well established with the town's upper classes (to use a poor phrase but social context is important). Jane Duncan was admitted to the 1st Presbyterian Church in Pitts in 1821 by certificate and died in 1829. She was a wealthy woman and I have no idea where the money came from. I am putting this on the Tyrone list because the only reference I can find to Duffmount is in Co. Tyrone from an Ordnance Survey map site. I have no idea what it describes. I suspect John W. Duncan was some sort of commission merchant, as was his son. Thanks in advance for any suggestions for further research.
