Hello Gillian, If you are keen to research, you might like to look at Burney, which has this mention:
https://www.jstor.org/stable/23209371 . The instrument described is what Rollo Woods called a side-blown flageolet. He made one from an Aulos tenor recorder (one of the louder plastic tenors) with the beak enclosed in a piece of plastic tube, and a smaller oval plastic tube glued into the side. The whole was held like a flute. He played this to good effect on alto parts with The Madding Crowd in the 1970's. I'm pretty sure he must have known the Burney reference.
Besides Burney, there was John Hawkins book, overshadowed by Burney's which came out about the same time. Chappell's Popular Music of the Olden Time has a lot to read in among the music, and includes the period when recorders might have been used more widely. These books and similar are available online now, which makes searching possible, and research more efficient.
As for social conventions, there is evidence from the 17th century that violins were then regarded as unsuitable for church use, since they were played in the street and for dancing. Viols were preferred at this time, but this preference had clearly changed with Handel, Bach and Vivaldi. Biber was an early violinist virtuoso and composer of sacred as well as instrumental music. Vernacular woodwind and to a lesser extent strings were built by local craftsman in some places when professionally made instruments were unaffordable. The Briston cello, made of tinplate, is an example.
Best wishes, Mike
