I actually was just listening to the Bohola version posted above, and noticed some differences in lyrics as well. Here is my transcription of that version:

There was a lady in her father's garden
And a brisk young gentleman came passing by
He stood a while and he gazed up on her
And he said, "Young lady, would you fancy I?"

"I am no lady but a farmer's daughter
And a farmer's daughter of low degree
And if you want for to meet a lady
Travel further, don't fancy me"

"It's seven years since I had a sweetheart
And seven more since I did him see
And seven more will I wait upon him
For if he's alive he'll come home to me"

"If it's seven years since you had a sweetheart
And seven more since you did him see
Seven more you will wait upon him
Perhaps this young man you'll never see"

"Well if he's sick, sure I wish him better
And if he's dead, sure I wish him rest
If he's alive then I love him dearly
He is the young man I do love best"

That's when he saw that she'd been so true
He felt pity that she might be lost
"I am your true and your single sailor
That all this time did the ocean cross"

"Well if you're my true and my single sailor
Your face and features seem strange to me
But seven years make great alteration
And the raging seas between you and me"

He put his hand down into his pocket
His lily-white fingers being thin and small
Drew out the ring that they'd broke(?) between them
And when she saw it down she did fall

He lifted her in his arms so dearly
And he gave to her love and kisses three
"I am your true and your single sailor
I've come from sea, love, to marry thee"

So come all ye young fair and tender maidens
Don't slight your sailors whilst they are at sea
For when they come home they'll make you their own
And they'll bring you o'er to Americay
