I would add "Enrichetta" to the Italian variants. It's very rare, but not impossible. My ancient Greek teacher was named Enrichetta. Granted, she was very old. https://en.wiktionary.org/wiki/Enrichetta [noted -ed]
I love this version of Martha, it sounds kinder. I especially love the diminutive "Marfusha"! I heard it in Road to Calvary and I thought it was so sweet!
