Thomas and Hannah were both from Ireland and were from unknown (at least to my knowing) parentage. They were born around 1830 and came to Vermont as either late teens or young adults. They had at least 6 children, 5-6 others popped up on records but either died young or were mixed up with other Grangers. There verifiable children are Katie Granger, Patrick Granger, Bridget (Granger) Sullivan, Edward Granger, Walter Granger, and Ellen (Granger) Buckley. Me and my close family descend from Walter and his 2nd son Edward Henry Granger Sr.
