I do not have info on this, but do have general info that may help you to get more from this source.
You may want to include any names of people that were known to the mopther and or father at the time, school's gone to, friend's anmes, churches in the area you grew up, places you hung out and with whom, stores you frequented, parks nearby and time frames for anything listed, relative's names if known, etc. These are a few of the things that may jog a persons memory and give you some info to use4 in your search.
