Macartney, M.P. Belfast. 1700s.
"A History of the County of Dublin" p.77 DALKEY, extract :
" A cotton factory, which was totally destroyed by fire, had also been established in the town, on ground belonging to Mr. Watson of Bullock".(Mr. Watson was my relative).
At the close of the 18th century one of the principal inhabitants was Mr. William Macartney, father of Sir John Macartney of Rochestown (south Dublin), who had represented Belfast in Parliament for many years.
Was this Macartney family in business in Belfast with the Adair family ?
