The only 2 Paddock's mentioned in the book are:
Lewis A. Paddock
William Robert Paddock
However in the Historical Encyclopedia of Illinois there is a brief mention of a Mr. and Mrs. Philo Paddock:
Some First Things and Early Happenings:
Births in the county:
Osbert Paddock, son of Mr. and Mrs. Milo Paddock in October 1836 in Benton Township.
But no other mentions of Philo and none of Henry.
