There's a note on your John's father's page: "John "Jacob" Snavely was born about 1717 and died around 1790 in Montgomery County., VA at the age of 73. John died in testate about 1790 and Peter Snavely was executor of John's Estate. One of John "Jacob" Snavely's sons was also named John and he was born between 1750 and 1760 in Montgomery Co., VA. For John's second marriage he married Elizabeth Martin on 28 Dec 1816 within the same county. John died about 1833 in Montgomery Co., VA. Of the several children that John and his first wife (unknown to this writer at this time), William Snavely with other associated families, came to La Porte County, Indiana."
The person putting up the genealogy, E. Tostini-Schneebell is Italian, but she seems to have some english.
