I have not been successful in locating the family in prior years.
The information contained at the previously cited website seems to be mostly correct. That information tells us that James Coffey a son of an unnamed Coffey and Jane Brown, married Margaretta Pemberton McConnell.
Their children were:
George A., born Dec. 20, 1820, died Feb. 20, 1864 in Philadelphia, PA (?)
Catherine E., born Jul, 24, 1822, died after 1886, m. Alexander P. Robinson
Titian James, born Dec. 5, 1823, Huntingdon Co., PA, died Jan. 11, 1897
m. Mary Kerr Feb. 13, 1855
Henry T., born 1827, Huntingdon Co. (probably); died after 1886
Thomas Pemberton, born May 25, 1834, Huntingdon Co.; died Feb. 8, 1886
Lewis S., born abt. 1838
Titian's age in 1880 would seem to indicate that he was born closer to 1824 or 1825. Refer to the website for more information.
