Kafildia Noodle?

My (step/bonus) grandmother came to the USA from Leipzig Germany before WWII. She made a soup type dish called kafildia noodle. I have her hand written recipe card, and that is how she spelled it. The recipe is simple. 1lb hamburger, onion, 1 egg, salt and pepper.
Then the noodle is 1 1/2cup flour, 2 big spoons of water, 2 eggs. You make the noodle dough and roll flat. Then spread the meat mixture thinly over the dough. Roll it up, cut into 2" pieces and boil in beef broth. She always added carrots and celery to the broth, but that isn't in the official recipe. While I am not of German decent, I spent a lot of time with her. As far as I can tell I am the only one who is keeping this recipe going. My step siblings all love it, but have never bothered to learn how to make it. I have searched online many times for it, and have never found anything close. Is this a German dish, or maybe just a unique family recipe she shared? It isn't fancy, but it is amazing on a cold winter day. My husband and son have requested it for this weekend, as we are in the midst of a big freeze/snow.
My son wants to learn to make it, so the recipe will live on, even if it loses its German origins.
I am calling it a soup, but I am not sure that is accurate. The pieces are big, 2 would be an average serving in a bowl with some of the broth. If anyone has any information on this, we would love to know.
