The Houk Family: Pennsylvania to Iowa

I am currently researching my paternal HOUK line. Starting in Western PA, William Houk's (born c. 1808) family moved to the Lower Scioto Valley of OH -- eventually to Pike Co., OH. It was here that my G-G-Grandfather Jacob Houk was born(b. 1835). From OH, they moved to Wapello Co. IA in 1847. Here my G-Grandfather Francis Sherman Houk was born (b. 1875), and finally his son, James Francis Houk (b. 1899)-- my grandfather. If any of these names look familiar, please drop me an email so we can compare notes!
