Here's what I know, in brief, from historical records and anecdotes from relatives.
1. Capt. Thomas William HOWE was born 1808 in Tynemouth, Northumberland, UK. Christened on 1 Jan 1809 at Christ Church, Tynemouth, Northumberland, UK. Father: Thomas Howe Mother: Ann Pettit. He married Esther Emma Sutherland 1828 in County Cork, Ireland. She was born Abt. 1810 in Ballinasloe, Galway, Ireland, and died 07 Apr 1844 in Trois-Rivieres, QC. Thomas died 09 Aug 1845 in Trois-Rivieres, QC where was was Barrack Master at the time. Both of them are buried in the Protestant Cemetery, Trois-Rivieres.
Their four children were sent to the Protestant Orphan Asylum in Montreal, which had been founded in 1815 and was managed by The Montreal Ladies' Benevolent Society. The building that housed the orphanage was demolished in the 1960s.
2A. Maj. William Thomas HOWE was born 18 Jun 1835 at the Officers' Barracks in Fredericton, NB, and died Apr 1918 in Stanley, NB. He married Mary Ann Donald on 24 Jun 1862 in Fredericton, NB. She was born 31 Dec 1830 in Fredericton, and died Jun 1917 in Stanley. They had four children. Both are buried in Hillcrest Cemetery, Stanley.
Young William attempted to run away from the orphanage twice, and succeeded on his second try in 1847 and somehow made his way back to his grandfather's home in Penniac NB, where he lived until he married and moved to Ward Settlement (now part of Stanley). He had a distinguished military and political career, and a portrait of him hangs in the York-Sunbury Museum in Fredericton.
2B. Mary Fox HOWE was born 25 May 1837 in Ballinasloe, Galway, Ireland while her mother was visiting her family. A friend of the family, Colonel Fox, was asked to choose a name, and he named her for his wife and donated one hundred pounds to the family.
Soon after Mary was orphaned she was put in service to the Blake family in New Haven CT as a companion for their daughter. This family treated her very well, more like a relative than an employee. When she was about 20 years old she decided to return to her grandfather's farm in Penniac. She married her brother's friend Thomas Gilmore on 30 Jun 1859 in Nashwaak, NB and they had ten children. She died 18 Aug 1907 in Penniac and is buried at the Penniac United Church.
2C. Jessie Callan HOWE was born 10 Mar 1841 in Trois-Rivieres, QC. She received a good education at the orphanage, and upon coming of age she returned to New Brunswick to become a teacher. She married Alfred Clark on 19 May 1870 in Fredericton, NB and they were living in St. Mary's Parish at the 1871 census. They had one child, Mary Ann Clark, before Jessie passed away suddenly from consumption. I've so far been unable to determine a date.
2D. Katherine Anne HOWE was born 23 Apr 1842, Trois-Rivieres, QC. Like her sister, she received an education at the orphanage prior to returning to New Brunswick. At the 1861 census she was living at the home of John Gilmore and family in Stanley, her brother-in-law. She supposedly went to Saint John NB to work, and died around 1880 without having married. I have as yet been able to find exactly when and where she died.
I'm also a Howe descendant:
Thomas W., William Thomas, Mary Anne, Ernest William Sansom (my grandfather).
