Hi Lee
Do you have a LDS Family History Centre near you? I'm just going through their online catalogue for Co Tyrone and came across the following:
Microfilm of photocopies of 11 charts (13 leaves; typewritten and handwritten) donated by Norma Geddes Cameron Scriver, Burlington, Ontario, Canada.
Original charts were created in 1960 by Arnold McNaughton. Additional information has been added in handwritten notes up to 1994. Some of the information was added by Norma Geddes Cameron Scriver.
Includes an introductory letter by Arnold McNaughton.
Includes Hamilton, Parkinson, Campbell, McWhinnie and related families.
Contains eleven descendancy charts on the Geddes family beginning with Andrew Geddes who died May 25, 1857. The Geddes ancestors originally came from Scotland. Andrew's son, Andrew, was born in 1822 in County Tyrone, Ireland. He married Mary Ann Cottingham in 1854. He died in 1899 in Ormstown, Quebec, Canada. The Geddes family immigrated to Canada sometime in the early 1800's and settled in southwestern Quebec. Joseph Geddes (d. 1862), another son of the first Andrew, moved to New York City. The charts contain primarily names and dates. The few localities mentioned include Quebec, New York, Vermont, New Hampshire and Florida.
I dont know if this would be in anyway related to your Geddes family from Co Tyrone.
Cheers
