Joyce, I am adding to Ron Tobias repsonse too. My line which is COY is connected to over 30 surnames that I have been following in the Greene/Montgomery Co areas.
I do have info about the Sidenstick,Ankeney and Koogler families.
I don't have all filled in on the Sidenstick/Ackeney lines, but did find in my database : Frank W Koogler b.1868-married Charlotte Haverstick b.1874-in Beavercreek Twp.,Greene Co. (they may be cousins to the one seek)
*I also have the father Frank M Haverstick b.1843-married (my line)Mary Catherine Coy b.1849-Greene Co.,Ohio
I found a few other marriages surnames you may be able to find something under. These are Beavercreek Family names that married Haverstick-Hawker,Snider,Swigert,
The Koogler family marriages in Greene Co. I have in may notes: Benham,Ankeney(3more between these families)Wolf,Harner,
*I have focused more on Greene Co.,and most of my research materials are of this area, but I do have some Montgomery materials to support the Pioneer families that went back and forth across the Dayton lines.
*The main people you seek: William Lewis Haverstick b.abt 1868 Frances Ankeney b.abt 1868-d.abt.1905 Children: George Haverstick b.abt.1888 ish?

**This Franklin M Haverstick is son of John Haverstick & Elizbaeth Holly-these parents had 8 known children.. *Perhaps it is one of these siblings you hail from There is William Haverstick b.abt 1840-died Dayton,Ohio (these looks like something) If you would like to email directly we can explore this piece * This couple had almost all boys of the 8 kids..Anyone one of them could have had a William b abt 1860-(the line you seek)
