He was named after his great uncle Gardner Johnson:Charles Gardner Johnson, and was known as Gard.  He was the firstborn child of William and Florence Boultbee, and was born April 23, 1907.  He was educated at Brentwood College, Vancouver Island Brentwood College, a boys' boarding school on Vancouver Island.
 He married Stephanie Hope Barbara Hespeler, Stephanie Hope Barbara Hespeler on August 4, 1931 and they had two sons, Boultbee:William Michael William Michael and Boultbee:John Jeremy John Jeremy.  The marriage broke down in 1938, and Stephanie took the two boys with her to Sydney, Australia Sydney, Australia in January 1939.

 About 1937/38, Gardner took ill and was advised to take some time off work, perhaps a few years, and to move away from the stress of urban living.  He chose to update the family history by travelling and visiting those who kept some of the records.  He visited Horace Boultbee in Toronto in April 1938 who supplied him the names of the descendants of Felix Boultbee:Felix Boultbee of Ancaster.  He visited the Reverend H. Travis Boultbee:Henry Travis, Rev. Boultbee in Evesham, England in the Spring of the next year who had a copy of TPB's history, and Travis allowed Gardner to copy it.  He travelled to Australia in November of 1939 to endeavour to patch up his marriage matters, and to visit and record the many family members living there.  He failed in the first endeavour, and succeeded in the second.  His most useful project for our family was the duplicating of photographs of Australian Boultbee men, including Edwin Boultbee:Edwin (b1790) Boultbee, the first to emigrate from England.  The duplicating was professionally done by the Kodak branch in Sydney.
 Gardner's daughter Boultbee:Helen Ann (b1944) Helen tells of her father's several ocean trips, when he would sign on as Ship's Writer and went around the world for $40.00.  In every port they docked in, he contacted any known relatives and they in turn would put him in touch with those they knew.
 Gardner sailed for home on March 1, 1940 aboard a petrol freighter bound for Los Angeles. He was the only passenger, and made this note in his diary:
 The great thing about travelling on a ship like this is the informality of it all.  Have worn the same shorts and sandals for the last two weeks -- not even a shirt -- no more passenger ships for me.  The Captain is most entertaining & never tires of telling of his experiences.  Have read about ten books & written numerous letters -- it's grand chance to finish the things I've started.
 He arrived home in Vancouver on April 6th.  Within a few weeks, he was arranging to lease some property in the Cariboo District, B.C. Cariboo District of British Columbia.  He had seen the property in the Spring of 1939, and must have considered that it represented the change in life-style that his doctor had recommended.  The property was about 300 miles by road northeast of Vancouver, and was 13 miles from the home of Mr. & Mrs. Larsen:Mr. & Mrs. Larsen, whose daughter Larsen:Mabel H. Mabel later became Gardner's second wife.  The nearest post office was at Bridge Lake Bridge Lake.
 Gardner kept his Diary of Gardner Boultbee diary until June 1, 1940, and returned to making entries on January 1, 1942, with this note:
 Since my last entry in this book I have been busy developing the ranch.  The most eventful happening in the past year was my marriage to Mabel Larsen:Mabel H. Larsen on August 1st. My life is at last complete.
 He continued the diary until March 29, 1942 and did not pick it up again.  There are three significant entries of family history:
 Saturday, January 3, 1942:  These three men are working on Mother's house and still have a lot to do before she can move in.  [Gardner's Nicholles:Florence Una mother was having built a new summer-house at the ranch.]
 Tuesday, February 24, 1942:  A letter from Mother says that Hespeler, Stephanie Hope Barbara Stephanie has arrived in Los Angeles with Boultbee:William Michael Michael & Boultbee:John Jeremy Jeremy -- thank God the kiddies are safely on this side of the Pacific.
 Saturday, March 21, 1942:  Ole [Larsen:Ole Larsen] gave Mabel a milk cow -- we are most grateful because when the baby arrives we will need a lot more milk than our one cow is giving.
 Gardner & Mabel had five daughters.  He was an active family historian and corresponded with the Family worldwide from 1939 to 1948, and from 1977 to 1980.  During the latter period, he corresponded regularly with Patrick Boultbee:Patrick Horace Boultbee in Willowdale, Ontario, and upon Gardner's death, his widow, Mabel, gave his genealogical files to Patrick.  It was a most considerate gift for the Family, and has aided greatly in the preparation of this book.

 Gardner died August 2, 1980 while vacationing in Barbados Barbados.  He was cremated, and his ashes distributed at Lac des Roches at the place where he proposed to Mabel.  She died in 1987.
