That is wild using old gravestones to pave the path. Really intriguing find and capture, Helen! You're right about the relativity of "oldness," None of the buildings in the US can compare in age to many of those in the UK!
An interesting case of recycling the past - what is also interesting is that the lady was only 35 when she died; today that would be considered quite young but perhaps in her day that was a good age to reach!
At least the stones were useful and not totally dumped.I have an interest in gravestones..comes from having a very pleasant ,sunny,happy cemetery to walk around as a kid and an older brother with an interest in genealogy!
