I don't believe that Geordie and Laszlo are even remotely related, or can usefully be considered analogous; Child #95, The Maid Freed from the Gallows, has more significant elements in common with the Hungarian song, for what it's worth, including, in a Swedish analogue, a series of curses. Tradition is full of thieves of cattle and horses, but the cumulative ransom motif of Laszlo and Child #95 is, I suspect, the clincher here; it does not occur in any variant of Geordie.
