It's sad what propaganda will do to a sweet love story.

David Williamson was a preacher and covenanter, a denomination that was cruelly repressed by the English authorities. He was fleeing a passel of soldiers (no doubt a bunch of thugs) when he came upon the house called Cherrytrees.

(You don't suppose the soldiers were going to ask him for some ID, urge him to respect curfews, and let him be on his way, do you?)

As it happened, the window into which he shot belonged to the daughter of the house. Now,if you have ever read the fiction of P.G. Wodehouse, you know that when a man slips into a bedroom at night, he is bound to knock over a table covered with china dogs or to step on a cat's tail. This is precisely what the Rev. Williamson did. He collided with a bunch of tirly-whirlies (knicknacks), and they o'd. (Went over.) Bertie Wooster would tell you that it happens every time.

The daughter of the house looked upon his curly hair and his small but no-doubt-manly form, and saw that it was good. She did not want the soldiers to break his limbs or fracture his skull, so she hid him. In time she married him.

As for all that stuff about her being unmarried and pregnant (how likely is that?) and Williamson having five or six wives - remember all that was in an account by his his enemy and persecutor. It behooved him to make Williamson look bad.

As for 'leeze me on', it is a corruption of 'lief is me,' as mentioned already. the 'me' here is dative, so the phrase simply means

dear is to me your curly head.

Hurray for love!
