For "One misty moisty moring (The Wiltshire Wedding) see the Opie's 'The Oxford Dictionary of Nursery Rhymes' and ZN73 in the broadside ballad index on my website (tune is B149 there).

"My Love's in Germanie" is Hector MacNeill's song to "Ye Jacobites by Name" (Scots Musical Museum #371), which is evidently the early tune for "Captain Kidd" (see original "You Jacobites..." and its tune direction in Scarce Songs 1).
