An edit for you to consider:
Holly - It is a genus of small, evergreen trees with smooth, glabrous, or pubescent branchlets
- A common western name (western Europe might be less common, quite common in England, Canada and the USA)
Molly - A common western name (western Europe might be less common, quite common in England, Canada and the USA)
Holy - used in exclamations of surprise or dismay.
Moly -
Moly is a magical herb mentioned in book 10 of Homer's Odyssey.
Now I included all the words so you could search the combos yourself since anyone who lives where the phrase is common would know: Holy Moly - means wow that's amazing approximately where Holly Molly would be a first and middle name or first and last name not an exclamation. You can test this by typing (or copying) "Holy Mol" (without the "") and before you even fill in the last letter it should pop up 6+ search suggestions with Holy Moly and do the same with "Holly Mol" and you should find fewer suggestions directing to Holly Molly.
Where did the phrase holy moly originate?
Holy Moly (also spelled Holy Moley) is an exclamation of surprise that dates from at least around 1892. It is
most likely a minced oath, a cleaned-up version of a taboo phrase such as "Holy Moses".
Having seen this phrase repeatedly the easiest way to edit this would be to replace all holly molly instances with holy moly and repeat with capitalized versions and first word capitalizations. I hope this assists you in your endeavor.
