I found this on the Net which was printed in 1853 in the Albany NY Argus newspaper, concerning the probate date of the will of Pontius Howard:
"The people of the state of New York, to WILLIAM HOWARD of Michigan, CHAUNCEY HOWARD of Wisconsin (note 1), SARAH LYMAN and ______ LYMAN her husband of Connecticut (note 2), JAMES HOWARD of Illinois, but whose particular places of residence are unknown, and cannot upon diligent enquiry be ascertained, and to LUTHER J. DORWIN of Watertown, Jefferson County, N.Y., special guardian of SARAH M. HOWARD and NANCY HOWARD, (note 3) minors, &c., constituting all of the next of kin and heirs at law of PONTIUS HOWARD, late of the town of Henderson, in the county of Jefferson and state of New York, deceased, send greeting.
"Whereas, WILLIAM P. SMITH, the executor named in the last will and testament of the said PONTIUS HOWARD, deceased, has lately applied to our surrogate of our county of Jefferson, to have the said will proved, as a will of real and personal property, in pursuance of the statute in such case made and provided, you and each of you are therefore cited and required personally to be and appear before our said surrogate, at his office in the village of Watertown in the county of Jefferson, on the 11th day of April next, at ten o'clock in the forenoon, then and there to attend the probate of the said last will and testament.
"In testimony whereof, we have caused the seal of office of our said surrogate to be hereunto affixed. Witness JAS. R. A. PERKINS, surrogate of the said county of Jefferson at Watertown, the 18th day of February 1853.
"JAS.R.A. PERKINS, Surrogate"
1. Chauncey Howard (1787 to 1878) and his family were at this time living in Farmington, Fulton County, Illinois.
2. This can explain the first name of Lyman Howard, son of Chauncey Howard and his wife Mary Briggs, who was born in Dutchess County, New York on 12 June 1823. There seems to be at times other uses of relatives' surnames as first names of Howard children.
The second son of Chauncey and Mary Howard was Clark Howard, born on 15 December 1811 in Dutchess County, New York. Perhaps CLARK was the maiden name of Chauncey's mother, SARAH, the wife of PONTIUS HOWARD? Sarah Howard died on 23 April 1851 at the age of 92 years and is buried in the North Cemetery, Hungerford Corners, Jefferson County, New York.
3. Sarah Howard was born in 1846 at Henderson, Jefferson County and Nancy Ruhama Howard was born on 7 March 1848 at the same place. There parents were Thomas Howard (1796 to 1849) and Lovina of Henderson. Thomas was a farmer and died in April of 1849, age 53 years. Shortly after the 1850 Census, his widow Lovina remarried to Henry Cook of Henderson and over the years had more children. Luther Dorwin would have been a special guardian for the two Howard girls for purposes of their inheritance from their grandfather Pontius Howard.
