John Templeton (1766–1825) was a pioneering Irish naturalist, sometimes referred to as the "Father of Irish Botany". He was a leading figure in Belfast's late eighteenth-century enlightenment, initially supported the United Irishmen, and figured prominently in the town's scientific and literary societies.

Mary Ann McCracken was a social activist and campaigner in Belfast, Ireland, whose extensive correspondence is cited as an important chronicle of her times. Born to a prominent liberal Presbyterian family, she combined entrepreneurship in Belfast's growing textile industry with support for the democratic programme of the United Irishmen; advocacy for women; the organising of relief and education for the poor; and, in a town that was heavily engaged in trans-Atlantic trade, a lifelong commitment to the abolition of slavery. On International Women's Day 2024, a statue of Mary Ann McCracken was unveiled in the grounds of Belfast City Hall.
