Born to a working-class family in 1745, Asbury lived in Newton Road, Hamstead.
The Bishop was a humble metal worker when, in 1771, the founder of the Methodist Church John Wesley called for men to become preachers in the soon-to-be-independent America. Asbury answered the call and his passion and determination meant Methodism became important in the founding of the young country.
He travelled a remarkable 225,000 miles on horseback where he preached to anyone who would listen in the burgeoning New World.
On the family fun day on Saturday, members of the Methodist church from Baltimore and Philadelphia spoke about his 'incredible impact', which made him one of the most significant religious leaders in American history.
Reverend Fred Day, general secretary of the united Methodist church general commission on archives and history, said: "Francis Asbury was a gift given from the Black Country to America, and can only be described as an unsung founding father of religion in America."
