Below is part of my posting on another "William Reynolds" thread which can be found at:http://boards.ancestry.com/surnames.reynolds/3687/mb.ashx
This thread goes back to 9 Jan 2002.
I don't know that I am related to the Reynolds family being discussed in this thread. My 2nd GGF was William C. Reynolds (c. 1810-1884, Pennsylvania, d. Illinois). He md. Catherine A (or Ann C, depending on which census is "consulted") [...]. Their children, all born in PA per census information, were:
Mary E (c. 1833), John R (c. 1835), Sarah J (3 Jul 1839), William (c. 1841), Samuel (c. 1844)
As you might guess by the complete birth date, Sarah J was my GGM. Per her family Bible (which I think she purchased in 1872), she married Martin Florida (1840-1909) on 6 Mar 1862) in Mercer County, Illinois.
Your William is a little too young to be one of mine, but since you mention two states (PA & IL) connected to my Reynolds, I will add that my GGM's Bible also states that she was born in Washington County.
