FWIW Wikipedia says the original had 8 verses, it was expanded by the author at the request of the local bishop.

Here's my own on the fly translation of the long version presented in the PDF:

O Virgin Marie,
The Christian people
of Lourdes pray to you
To you they come

Let us sing your [hi]story
In your city/place
From the heights of glory
deign to hear us

11 of February:
One day Bernadette
was picking up wood
with two little girls
who were crying from the cold

Out to Massabielle
the child wanted to go,
but she is so frail;
how can she get across?

Cold had seized her
and a sound surprised her
but on the prairie
there was no wind

the base of the rock
suddenly shined
The Woman approached
and signed to the child

The white apparition
appeared to her eyes
like a presence
that speaks of God

With a diadem
made of light immortal
she had for her belt
a ribbon of heaven

At the foot of her Mother
the child, who saw her
learned to well
make the sign of the cross

The beads of a rosary
ran through her hands
and of that prayer
she traced the way

for a long time Bernadette
remained before the rock
happy, repeating
the song of the 'Ave' [Hail Mary]

14 of February
She was so beautiful
how to see her again?
What does she want of me?
How to know her?

She came back
without saying her name
the child, all mute
had fear it was a demon

with a sudden gesture
holy water sprang forth
to the timid child
And the Lady smiled

18 February
"You have come
to Lourdes to us
Poor beyond telling
Who am I for you?"

"Come, I beg you
here 15 times
with your friends
listen to my voice"

"the generous child
one day, I promis
to make you happy
in heaven forever"

19-23 February
The believing crowd
coming back each day
with a humble bearing
watching each return

Her [Bernadette] eyes illuminated
her front/face paled
because she, could see
the infinite world

The faithful people
foreshadowing our day
a new era
had started for them

the Lady has left
how to see her again?
the child dazzled
kept her hope

22-26 Feb.
Two times the shepherdess
came back to pray
without light
the rock didn't shine

"one says that at the grotto
I made everything up
my mother is sobbing
and they want to arrest me"

24th of Feb.

The unknown Woman
quickly reappeared
the child saw her
and found once again peace

"Know that the storm
will one day be passed
that your courage
will return stronger than ever"

The child supplicated Her:
"What does your heart say?
I want that people pray
for all sinners

with insistence
the Lady three times
said "penitence!"
Christians, this is for you!

"Eat the bitter herbs
that are growing in the dirt
and in the dust
cover your face"

25,27, 28 Feb.
"At this fountain
Come and bathe
in the water pure and holy
come, all of you, and bathe

The font is close
attracting in an instnat
a sign from the rock
comes back the child

As soon as she thinks it
quickly she sees
springing forth the bubbling water
from the ground into her hands

O fountain of life
that brings back health
blessed fountain
how we sing [thy praises]

2-4 March
"I want that right here
at the foot of these hills
the people that I love
come and process"

"and that a chappelle
be built in this place
to remind men
that they must pray to God"

"come; say to the priests
the wish of my heart
the priests must rekindle
a speaking sign:

"ask for a sign
says the pastor
that of a wild rose
to spring forth a bud"

"Go back and tell
to your pastor"
"who is this Woman?
her name, I am waiting on"

With a smile
welcoming this wish
The Woman wanted to say
"I will do one better"

25 March
The earth is rejoicing
The Living God wishes to save us;
The Church repeats
the song of "ave"

O gives you, the earth
admire this gift
what is this mystery
of Your holy name?

Three times the shepherdess
asked again humbly
the same prayer:
the Woman listened

Mary to the earth
will give her secret
by this shepherdess
that no one believed

Virgin Immaculate
and now you all believe
finally revealed
Your true name

7 April

The candle that burns
saving one's fingers
follow the incredulity
[he] who doubts and who believes

16th June

The faithful virgin
comes back but unspeaking
she is truly beautiful
unlike any other

18 Jan.

Faithful, hear the message
that the Church has spoken
giving testimony
to the truth

"Mary has come
here to us 18 times
The child who saw Her
is worth of belief"

...here I give up on couplets 48-60. This is too stinkin long and not worth singing in its entirety.

I've done some research on this hymn and its origins and a discussion here on CMAA forum There are links in the discussion pointing to French hymnals dating a few years after the apparitions of Lourdes where evidence of the melody is found. I think probably the link most on topic French Priest Jean Gaignet

Also, here is a copy from Tozer's CATHOLIC HYMNS, 1898. Tozer was probably the first to introduce the 5 Ave's which is typically found in hymnals today

And Don, thanks for the 1898 hymn. The text is more elegant than my verses (even if it's not really based on the original French lyric). I'll definitely pitch it to my pastor. Thanks again!
