Dr. Christopher William Flock was born on the 12th of March, 1831 in Toronto.  Dr. Flock was the eldest of 4 children born to William Flock and the former Mary McAvitt.  His siblings were; John, James and Mary.  Dr. Flock was educated in Toronto at James Hodgson’s Commercial and Classical Academy which was located on Colborne Street.

In 1845 he started studying medicine at Rolph’s Medical School, which is now called The University of Toronto Faculty of Medicine.  Dr. Flock passed his medical board exams in 1850.  He appears on the 1851 census, as practicing medicine in Nelson Twp, Halton County.

Dr. Flock married Helen Elizabeth Nelles on the 17th of November, 1852.  She was born on the 29th of May, 1829 in Grimsby, Ontario, the daughter of William Nelles and Mary Ann O’Reilly.  Her father died when she was 10 years old and it does not appear that Mrs. Flock had any siblings.  Her grandfather was Col. Robert Nelles, a militia officer, politician and businessman.  He built a large mansion located at 126 Main Street West in Grimsby.  Here Mrs. Flock’s father was raised with his many siblings.  The mansion still stands today and is a museum.

In 1858, Dr. and Mrs. Flock were living in Oakville, Ontario.  For a time, Dr. Flock was a member of the Oakville City Council.  By 1861 Dr. and Mrs. Flock were living in Westminster Twp in Middlesex County.  Dr. Flock joined the College of Physicians and Surgeons on the 14th of June, 1866.

According to the 1871 census, Dr. and Mrs. Flock were living in Port Stanley, Elgin County with their 8 children; William, Helen, Mary, Sarah, Fanny, John, Edith, Carrie and Robert.

Prior to 1880, Dr. Flock and his family were living in Lucan in Middlesex County.  The Donnelly massacre occured near Lucan February 4th, 1880.  A vigilante group killed 5 members of the Donnelly family in Biddulph Twp.  Dr. C. W. Flock performed autopsies on the murdered family members and testified in court at the trial of Jim Carroll, who was accused of murder in the Donnelly massacre. (Jim Carroll was acquitted.)

Not long after living in Lucan, the family moved to Leamington, in Essex County.  It was during this time, that Dr. Flock saw patients in Wheatley and Romney Twp (Chatham-Kent), due to the close proximity (approx. 12 km). Dr. Flock’s name appears on a number of birth and death records, as early as 1882.  His daughter Fannie died in Leamington on November, 1st, 1883.  She was about 20 years old.

Around 1885 the Flock Family moved once again, to St Thomas in Elgin County.  Dr. Flock advertised his medical practice in the 1885 Farmers and Business Directory for Elgin, Middlesex and Oxford Counties.  Dr. Flock was a member of the Canadian Order of Foresters, the Ancient Order of Foresters and the Knights of Pythias.

In 1890, Dr. Flock moved his family to Bancroft, Nebraska.  Mrs. Flock died in December of 1907 and she was buried at the Blair Cemetery in Blair, Nebraska.  After his wife’s death, Dr. Flock moved to his son’s home in Emerson, Nebraska.  He no longer practiced medicine.  Dr. Flock died at the home of his son, Robert Nelles Flock on the 10th of March, 1911.  He was buried next to his wife at the Blair Cemetery.  Cemetery officials advise that there is no tombstone on their graves.
