According to a local Manitoba history and Canadian census records, Edward Pierce Langrell came to Canada around 1869, after attending Dublin University. He lived in Ontario where he moved around, teaching school in small communities. He was living in Port Arthur in 1882 when he married Mary Elizabeth Trevillion. He moved his family to Edmonton, Alberta for several years before moving to Woodlands, Manitoba around 1888. He was a pioneer in both locations, helping to shape communities as a farmer, teacher and local politician. He died in 1924 in Manitoba.
I'm not sure how many children were born in the family, but there were at least 4: John Edward (1886- ), Mary Amelia (1888-1894), Francis Trevillion (1890-1937) and Henry Grattan Guinness (1893-1979).
