Are there two William Beard b. 7,1760

I have tried to find two William's born in July , 1760 in Carlisletowne, Pennsylvania there is some disagreement about William Bread who was in the Rev.War in South Carolina .

The first William information is as followed.
Born July, 1760 Carlisle Town ,Pennsylvania married to Eleanor Irwinand William Died May 20, 1809 .
I have not been able to find any document to support this. Other are not able or wil notsupply me with any information where I may obtain copies to clear this up.

The second William born July ,1760 in Carlisle Town , Pennsylvania . Wife died in Alabama he moved about and died in June 4, 1847. Only living son was James A. Beard lived in Union County, Ga.

Any one can find this in the Absrtacts of The Revolutionary War Pension Files. the second William is my line . and Family has it that William married Margeart Blackstock.
William and John his borther married sister in the Blackstock family.
All I ask is to help me find the first William so that I may prove or disprove and move on.
Any taker!!!!!!
