There are two versions of "Seventeen come Sunday" in the DT under the reference given by Bruce, but neither are the Somerset version.. There are also several versions of "The lowlands of Holland" . Bruce has identified a source for "My Bonny Boy" above.

The CUTTY WREN is in the DT here ; BLOW AWAY THE MORNING DEW, (child 112) is in the DT here; HIGH GERMANY here and JOHN BARLEYCORN. here. I'm still looking for "Whistle daughter whistle"
