Hi Jeff,
Thomas and Harriets son Thomas McCabe was my grandfather,
He married Mary Ellena Murphy, they had 6 children Kevin, Jack, Vince, Patrick, Marg, and my mother Agnes, Patrick is the only one surviving.
I believe Thomas and Harriet actually had 12 children the 6 you named plus Mary, Hugh, Patrick, Robert, Dora, and Marguerite. My grandfather named one of his sons Patrick and one of his daughters Marg after Marguerite, this suggests I may be right.
Best Regards
Brian Smith
