I grew up on Ayrshire Farm in Upperville where the Ayre's lived. Thomas died of wounds in Cashtown, PA after Pickett's Charge in the Battle of Gettysburg. If I remember correctly Edward and Annie B. settled in Waterford, VA. One of the female Ayres died in childhood I thought. At any rate a number of them are buried at Ivy Hill in Upperville right at the entrance of the cemetery. I will try and find my notes, but if you make it to Upperville you need to look up Welby Kenny.
Also, the Benton farm in Middleburg is something to see if you haven't already. It's called Huntlands.
Take care good luck.
