I am also from the Mary Ann/James McGovern line.
Mary Ann had a brother Patrick who was married to Elizabeth Forrest. Patrick was killed by a train, July 1894
He was living at Bothwell Park Colliery at the time.
I also found the County Wicklow baptism for Mary Ann but couldn't find a death for Elizabeth Teevan in Ireland. I found it unusual for someone to come to Scotland from so far south in Ireland and wondered if they moved to England first and came to Scotland after Elizabeth died
