My grandfather, Patrick, built the little house in the lower left corner for his brothers, Tom and John. It and the little white garage - center left = are long gone as is the barn you can see some of almost in the center of the photo. The big oak in the center blew down several years ago which opened up the yard a bit.
Mom and Dad built the house - center right - in 1964. It was renovated in 2002 and that's where I live now. We took down the old barn (before it fell) and have put up three buildings behind and to the left.
