Your LYERLYS were from Rowan Co., NC then to Union Co., IL. A great deal of work has been done on them by members of the LYERLY/LILEY family in Bollinger Co., MO. You might make contact with them through that USGENWEB query. You might learn more by seeing my book "German Speaking People West Of The Catawba River IN NC 1750-1800 which is available in most major libraries.

Good luck,
Lorena
