"George Clinton CALEF, senior member of the firm of Calef Brothers, is a
native of Vermont, and was born in Washington, that state, June 19th, 1837.
He was the son of Cutting S. and Martha Paine Calef, and was brought up on a
farm. His father was a leading business man, but died at the age of 47,
when George C. was seven years old. His wife, Martha H., belonged to one of
the first families of Barre, VT. She was born in 1801, and died in 1885.
Their children were: Ezra P., Warren H., Alden D., Ira C., Quincy O.,
Miraette A., Elmer Norton, Cutting S., and George C., Martha, Lucy A., and
John F. Ezra went to Illinois, Alden to Boston, Ira to Providence, Elmer
N. to Oregon, Cutting S. and George C. to Providence. Martha died when
young. The others settled in Washington. Elmer N. died in Oregon, in
December, 1890, leaving a wife and 12 children. Cutting S. died in
Washington, Vt., but had always resided in Providence.
George C. Calef remained on the farm until he was 21 years old, receiving
in the meantime a common school education, with a few terms at the academy.
In 1858, he came to Providence and began working for Abner Gay, Jr., in the
market business on the corner of North Main and Thomas Streets, and in 1859
Ira C., Cutting S. and George C. Calef became successors to Gay, and
business has continued at the old stand, and under the same name (Calef
Brothers) ever since. In connection with this enterprise in Providence,
which is the largest family market now in the city, the house has also done
much western business with Chicago. They also have a branch store at
Lonsdale, and employ in all from 20 to 25 hands, in a business which amounts
to $200,000 annually. Mr. Ira Calef in time retired from the firm, and was
succeeded by Charles H. Jefferds. After the death of Cutting S. Calef and
the retirement of Charles H. Jefferds, Clarence Kingsbury and Louis A.
Gladding were admitted into the firm. Mr. Calef also owns a large livery
stable on Battey Street, Providence, in which over 50 horses are kept.
Mr. Calef has taken great interest in educational work, and has been trustee
of the Manton school district for ten years, and still holds that office.
Through his efforts, largely, the first high school was established in
Johnston. He has been a member of town council, is a member of the
executive committee of the Butchers and Marketmen's Association, an active
member, and one of the executive committee of the Sons of Vermont, president
of the Manton Building and Improvement Association, president of the
Olneyville Free Library Assoc., and chairman of the building committee, and
has taken great interest in securing the elegant and costly building now in
process of erection, to be devoted to library and other uses. The
improvements at Manton are largely due to his influence and enterprise in
securing Pawtuxet water, street lights, telephone communication, curbed and
graded streets and horse cars. Mr. Calef has always had a good opinion of
real estate, and has invested largely in that kind of property. He built
his commodious residence in 1874. Mr. Calef is a keen observer, and with
his wife has traveled considerably, they having visited 45 of the 58 cities
in the United States, having a population of 50,000 and over.
In September, 1855, he was married to Emma Sanders, daughter of Richard and
Almira Sanders, of Providence, and sister of Cutting S. Caleb's wife, and is
the father of seven children, six now living, viz.: Irene L., Herbert C.,
Mabel S., Frank T., Edith and Helen B. Richard Sanders was a successful
business man, highly respected by the citizens of Providence, and was a
member of the legislature at the time of his death in 1868. Mr. Calef and
his family attend the First Universalist church of Providence, and he is a
man who finds his chief pleasure in his home and family and in extending
hospitality."

"CALEF BROTHERS, Choice Family Marketing, No. 79 North Main Street. -- One
of the oldest and largest family marketing businesses in Providence is that
conducted by Messrs. Calef Brothers, whose meats and provisions are always
to be relied upon as the choicest and best the market affords. The
undertaking was established at this location in 1840, and came into the
hands of the present firm in 1885, the copartners being Mr. George C. Calef
and Mr. L. A. Gladding, the latter of whom was previously engaged with the
house for eight years. Six years ago, a branch was inaugurated at Lonsdale,
R.I., where now eight competent assistants are employed and five wagons
retained for delivery purposes. The extent of the firm's operations may be
fairly gauged from the fact that they cut up twenty sides of beef per week
at both places, besides selling a large quantity of other meats, as well as
prime beef, tongues and corned beef as a specialty. The business controlled
here reaches throughout the city and suburbs, largely among the better
private families, necessitating the constant employment of fourteen skilled
hands and the retention of four wagons. The large store at No. 79 North
Main Street is fully equipped with all facilities and appliances for the
efficient handling and keeping of the heavy stock always on hand, the
ice-box having a capacity of six tons. Mr. George C. Calef is a native of
Vermont, and has resided in Providence for the past thirty-four years, and
rendered continuous service at the same stand and with the same firm until
the present time, and has been a member or a senior member of the firm since
1859, while Mr. L. A. Gladding was born in Rhode Island."
