Looking for information on my gr-gr grandmother, MARY WALSH, born abt. 1820? Ireland (Kilkenny?)arrived Canada 1845. Mary married Michael (Mic) Cathcart (1813-1887) born in Lingan, Cape Breton, Nova Scotia. Michael (Mic) and Mary lived in Lingan, and had 13 children: Mary (abt. 1847),Bridget 1847, Margaret abt. 1849, Annie abt. 1851, Michael abt. 1852, Catherine "Kate" 1853, William 1855, James abt. 1857, Ellen 1859, Patrick 1860, Theresa 1862,Michael 1865, Barney 1868. Daughter Bridget b.1847 is my gr-grandmother (she married John Burke, b.1851).
The 1900 United States Federal Census has Mary residing at Providence Ward 6 Providence, Rhode Island with Ellen J. Mulrey (her daughter?). It says Mary was born in 1820.However, the 1871 Census of Canada says Mary was 45, which would make her birth year 1826. Mary apparently passed away in 1911. Any information concerning her parents' names, siblings, etc., would be greatly appreciated. Thank you.
