In some cases, more of the context of a Leforge reference has been reproduced than may seem necessary.  However, the Leforges are a particularly fragmented family and, hopefully, by knowing the surnames that certain groups of Leforges were associated or allied with, we can come a step or two closer to putting the puzzle of our ancestry together.

Old Families of Staten Island by J.J. Clute -1877, p. 62.

The name of ________ De la Forge appears in the assessment roll of Boswyck (Bushwick) in 1676, and among those who took the oath of allegiance in Kings County in 1687, is the name of Adrian La fforge [sic], who had been in the County fifteen years.  In 1738 there was an Adrian Laforge who bought land on Staten Island.  From the similarity of the name, the inference is natural that if they are not identical, they were connected; this is, however, conjecture.  There appears to have been two branches of the family, the Castleton and the Westfield, who may or may not have had a common origin.  The paucity of notices in the old records of the County and churches, and the abscence of family records, renders it impossible to trace the family far.  The present living representative of the Castleton branch is Mr. G.M. Laforge of Illinios; the late Mr. Peter D. Laforge also of Illinois, and the late Capt. John Laforge of West New Brighton, were his brothers; their father was David and their mother Gertrude, daughter of John Martling (see Martling family); David's brothers were Peter, John, Benjamin, Jacob, Richard Channing Moore; Peter, David's brother was the father of Mr. Peter C. and David of Port Richmond.
Of the Westfield branch, we have only the following notices:
    David and Catherine had a son Henry Seguine, bap. May 15, 1790.
    John and Phebe Bedell married Sept. 15, 1804.
    James and Catharine Winant married Feb. 8., 1806
    David and Ann Johnson married July 8, 1807.

History of Vigo and Parke Counties: Together With Historic Notes on the Wabash Valley by H.W.
Beckwith - 1880

Almost at the same date of this settlement, so near in fact as at one time to throw some doubts as to priority, as settlement was formed on the army road, near the Lykins cemetery, and was known as the Lykins settlement. Amoung the first settlers at this point were David Lykins, Josiah Wilson, father of the late John Wilson, Esq., William Armstrong, and others. Between this date and the year 1820 some twenty-five or thirty additional families settled in the township and, as a few of their names and locations will indicate, spread pretty evenly over the township. Dr. E. Shattuck, on the army road, one and a half miles north of the Lykins settlement; William Paddock, near the present residence of George Farmer; William Foster, at the residence of J.D.E. Kister; Thomas and Athol Furguson, just east of the present residence of Joseph
Johnston; Armstrong McCabe, near the residence of E.T. Piety; Henry King, a quarter of a mile west of Daniel Johnson's residence; David Kelly, on the Kelly farm; James Johnston, just east, and William Thomas, just west, of the Baptist Church; William Drake, near the residence of Valentine Morgan; Isaac LeForge, at his late residence; Elijah Cayson, near the present residence of Caleb Kirkham; and Nicholas Yeager, at the present residence of Hugh Weir.
