Thomas Welch b.1816 and his wife Ellen b.1817 emigrated to America in 1851 with children Patrick b.1841 and Hanora b.1844. Family history has them coming from Waterford. I'm aware of the variant spellings, but in this case I am fairly certain of the spelling as they joined two other WELCH families in the state of Illinois.
Can anyone help---are there parishes where this particular spelling occurs?
