Tadgh Crowley was a pipemaker in County Cork, Ireland in the 1930′s. He was Pipe Major of several top bands in the Cork area, and even spent time in 1924 and 1925 taking lessons from John MacDougall Gillies. Crowley was also a popular Uillean piper.
George Hannah sent me this picture of a Crowley blowpipe that was on a MacDougall set -
