Can't remember exactly, but as late as about six or seven years ago, and about four or five visits since, two of them on New Year's Day. I love the place. I've also been informed of direct family connections to nearby Marlborough and Ogbourne St Andrew from 1820, going back at least to the 1500s, with possible Avebury connections - and they were all stonemasons, which raises the possibility their antecedents not only built Avebury but also helped dismantle it!
