Hi Susan, you have done a terrific amount of work as is obvious but are now bouncing on the reality that there is a finite genealogical brickwall where further links ie records do not exist. I have looked as hard as I can at your predicament, but have come to different conclusions. The Fergus theory is most likely a red herring. The 1901 census record reveals that both Isaac aged 83 and his neighbor presumably his son Isaac aged 43 can read but not write. The impact of this on previous enumerators cannot be underestimated, and on themselves. If this was true, and they were really Fergusons the whole time, it still leaves one other record that of a James Fergus who crops up in Griffiths Valuation in Saval More which is very close by to the west of Finnard. I couldn’t find further trace of this James in the census. Perhaps you have in the valuation revisions?
Trying to find earlier records of anyone surnamed Fergus in Co Down came to a halt. I had started with
1660’s Ulster Hearth Money rolls see
http://www.billmacafee.com for the most northerly counties inc co antrim but not including Co Down . There are no Fergus recorded, these are the spellings as found recorded and are just variations of Ferguson ie Fargason Fergison Fergisson Ferguson Fergusone ffargason ffargison ffargisonn ffergison fforgison fforgisone Forgison
Moving to specific records you quote
1811 to 1820 Townland of Tullymore. from Donaghmore Presbyterian Church Records-1785 to 1863
Finnard.
Robert Tedford; William Campbell; John Ward; William Crawford; John Scott; James Gibson; William Wright; Alexander Hannah; William Scott; Robert Bruce; James Campbell; David Campbell; Alexander Graham; Andrew Ferguson; James McGaw.
those Campbells being possible relations of jane
