Eric:
My name is Dan Hull and my mother's maiden name is Frew and her family is originally from Scotland. I researched some of my files and tools that I have and found that William H Frew possibly had a father named. Lemuel Frew and Melinda his mother. Lemuel was born in North Carolina and Melinda in Tennessee. According to the 1850 US Census William H Frew was 6 and he lived with his parents who were 38 and 26 in Cambridge City, Wayne County, Indiana.
William H had a sister who was 3 by the name of Louisa. In researching Ernest Paymond Frew, He had 9 children, Thomas Edward being the 8th.William H Frew and his wife Cytha had two children listed in the 1880 census of a daughter Emmer who was 12 and a son Orval who was 8 at that time. Orval was born in Indiana and Emmer in Tennessee. I have copies of the census and would be glad to share them. That is all I know. Thanks Dan Hull
