My 6th great-grandfather John McMillan was born in Scotland in 1736. He was a member of the Covenanters, a Scottish Presbyterian movement. Covenanters wanted and demanded perfect liberty of conscience and freedom to worship God according to their own faith.
The Covenanter's stand for political and religious freedom led to almost a century of persecution. Many, including John McMillan and his wife moved to Ireland then to America to escape the persecution. After a safe passage they arrived in New York in July 1764 along with their first three children.
My paternal grandfather was raised Methodist but didn't practice it and my dad converted to Catholicism when he married my mom. Though I consider myself a spiritual person, you wouldn't be wrong to describe me as fallen-away Catholic who still likes some of the rituals of Catholicism. And although I don't share my ancestor's commitment to faith I'm impressed by their persistence to practice theirs.
