The cover image shown below (from the Philatelic Foundation website), is addressed to H. Hale in Clinton, Ontario (Huron County). It is a registered cover (Canada Scott#F1) supporting a small Queen Victoria stamp (Canada Scott#37c) with an Auburn, Ontario, 1-split-ring postmark dated 18 May 1883.

This may be the famous lawyer/anthropologist/linguist Horatio Emmons Hale, Harvard grad, who married Margaret Pugh, daughter of William Pugh, also of Clinton. A web search will bring up a myriad of references relating to Horatio Hales's life, all of it interesting. Here are a few to get you started:

Horatio Hale's ancestors can be traced back to New Hampshire to his great-grandparents. I have derived a descendant list using the above cited genealogy site, however, I start with Horatio's parents. I purposefully did this because you all, indirectly, know his mother Sarah, as she was the author of the children's poem "Mary Had a Little Lamb".

Horatio married Margaret Pugh when her father William moved to New Hampshire after having accumulated a large land acreage in Clinton. Supposedly the oldest of their four children, Alfred, was born in New Hampshire but the next three children were born in what was Canada West, after the family moved to Clinton (Huron County) in 1856 to manage the estate left to Margaret when her father, William, died. The 1861 Huron County census form only shows Horatio, Margaret and daughter Florence but no Albert. Son William shows up in the 1871 census followed by Charles, age 3, in the 1881 census, making his birth year 1877.
The cropped image below is from the Longley Auctions website. The advert cover from Newsome and Gilbert, a typewriter/office supply company, is franked with a 2 cent Queen Victoria numeral stamp (Canada Scott#76) displaying a Toronto "orb" postmark/cancel dated August 1, 1899, addressed to Charles B. Hale, Clinton, Ontario, who quite possibly was Horatio Hale's son noted above.

Here is Horatio Hale's gravestone in the Clinton Cemetery (Gary Schumacher photo):
