My 2x great grandmother was Mary Cusack. I have two census entries for her stating her birthplace as Mayo Ireland.
She married John McGuire around 1850 and following the birth of Patsy (approx 1851) the family moved to Wednesbury Staffordshire England. Two further sons Hugh (my Gt Grandfather) and Edward were born in 1854 and 1860 respectively. John McGuire died between 1861 and 1871 and Mary died 1899 aged 77. From this I would guess she was born around 1822.
I am new to Irish research so can someone help me out here with some advice on what to do next?
