I don't know if this fits, but it is an old Irish song.

A YOUNG MAID STOOD IN HER FATHER'S GARDEN

A young maid stood in her father's garden,
Plucking roses all covered with dew,
A stranger came and gazed upon her,
And said, "Fair lady, will you wed with me?"

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

"Seven years it is since you had a sweetheart,
And seven more since you did him see,
And seven more you will wait upon him,
And perhaps that young man you ne'er will see."

"If he is sick, I want him better,
If he is dead, I wish him rest,
But if he's alive I will wait for him,
For he's the young man I love the best."

He put a hand into his pocket,
His sinewy hands they were slim and small,
And up between them he pulled a gold ring,
And when she saw it she down did fall.

He took her up and gave her sweet kisses,
And he embraced her so tenderly.
Saying, "I am your true and loving sailor,
That came from sea for to wed with thee.
