Early Life
Francis was born around 1727; the great Irish Famine (which killed hundreds of thousands) hit in 1740 when Francis would have been 13.
Career
Francis was the owner of a pub in Moy,
The Draper & Three Tuns and possibly also a linen draper (e.g. see P_Unknown_BryansLonsdaleBolland) though that could be a confusion with his son Richard.
Family
Some family records
1 state that Francis married Anne Cross of Darton in County Armagh. Others
2 give her name as Grace. Grace seems to be more likely as Burke's Landed Gentry
3 notes that Grace Cross (of the
Cross of Dartan family) married a Francis Bryant [sic]. The same sources notes that Grace had a sister, Anne, hence possibly the confusion.
There is clearly a marriage record for Francis Bryans and Grace Cross, in 1772, which would seem to put the confusion to bed. But just to add another element to the question,
the same source also indicates that a Francis Bryans married a Mary Clements in 1787: possibly a second marriage?
They apparently only had one child,
Richard, born in 1773 (Francis would have been 46 by then, which is very late for a first son; perhaps the others all died).
Death
Francis died on the 4
th of January 1830 in Moy, at the grand old age of 103.
