I'm helping my brother-in-law with the genealogy of his family and am I'm interested in the McKallagat family of Lawrence, Mass.
From census and vitals it appears that John (age abt 37) & Mary (age abt 38)(Kennedy) McKallagat/McElligott immigrated to this country abt 1858 with four children, Richard (about age 8), Thomas (abt age 4) and Mary (abt age 1). They had daughter Kate about 1859 after arriving in Mass.
They show up in the 1870 census as living in Lawrence, Mass, where they raised their family.
Any help with their Irish origin, family and emigration would be appreciated.
