Dictionary of National Biography, 1885-1900/Dallam, George
DALLAM, GEORGE (17th cent.), organ-builder, was doubtless a member of the same family as Thomas, Robert, and Ralph Dallam [q. v.] Very little is known about him save that in 1686 he added a chaire (i.e. choir) organ to Harris' instrument at Hereford Cathedral, and that the sixth edition of Playford's ‘Introduction’ (1672) contains the following advertisement: ‘Mr. George Dalham, that excellent organ-maker, dwelleth now in Purple Lane, next door to the Crooked Billet, where such as desire to have new organs, or old mended, may be well accomodated.’
[Authorities as under Dallam, Thomas and Robert.]
