Ogle (1846-1925) was born in Phillipsville, a small hamlet south east of Smiths Falls, the son of James Carss, who came from County Wexford, Ireland, and his wife, Alice Wilson, also from Ireland. At the age of 26, Ogle married Isabella Niblock, age 25, (1847-1937), daughter of James Niblock of Belfast, Ireland, and Sarah Ann Foster, of Rosscommon, Ireland. They had four children: Lila, (1873-1968), James, (1875-1934), Ethel (1877-1881), and Henry (1879-1882). Of the four children only Lila and James survived to adulthood. In a diphtheria outbreak the two youngest children, Ethel, age 4, passed away two days before Christmas, December 23, 1881, and their youngest, Henry, died three weeks later, on January 13, 1882. At that time there was no treatment nor cure for diphtheria.

Lila, like her mother, was gifted musically, and, following in her mother’s footsteps, she became a music teacher.

Lila, age 47, moved to Toronto in 1920 with her parents, when Ogle retired from public life at age 74. James, age 45, was already established in a law practice there. Both children remained in Toronto and chose to live out their years there.

The Ottawa Journal published this brief article on July 17, 1920:
Mr. and Mrs. Ogle Carss and daughter, Miss Lila, left on Thursday for Toronto, where they will in future reside. Mr. and Mrs. Carss were among the oldest and best known residents of Smiths Falls and their removal from town will be regretted by a large circle of friends. They had lived here for more than 40 years, and in all those years Mr. Carss had taken a prominent part in the life of the town. He had served in the council, and had been Mayor, and during his residence of two score years was actively interested in many enterprises.

Lila continued her career as a music teacher, and after her father’s death, she and her mother, Isabella, lived in a lovely home in the Forest Hill community. On Sunday, November 28, 1937, at her home, 393 Tweedsmuir Avenue, Toronto, Isabella Carss, died in her 91st year. Lila passed away in 1968, at the age of 94.

James studied law and became well known in the Toronto legal circles of his time. In 1921, at age 46, one year after his parents and Lila moved to Toronto, he married Mabel Kilner, age 25, daughter of William Kilner and Jemima Carroll. James and Mable had three children: Thomas Ogle Carss (1922-2015), Marjorie Kilner Carss (1924-2006), and Carol Isobel Carss (1929-2022).
