This is from a google search I did for monograms. I do not have the source other than I see the same font on pintrest and etsy. I am guessing it is a font that is downloadable for free since I have seen it used in a few places, but always with the same sample monogram as pictured. Any help is greatly appreciated!

The letters are modified from Adobe Caslon Bold Italic

download at MyFonts

Someone has applied three sets of swirls and swashes, one for each position of the letter (initial, central, and final) so that they interlock. It’s being sold as a vector alphabet on Etsy.

 

Thank you so much!!!
