I ended up doing a color-coded fan chart a few years ago to answer this very question.
Out of my 30 closest direct ancestors, 20 were Lutherans, one was born Roman Catholic but converted to Lutheran, three were Roman Catholic, and six were Reformed (aka thick-necked Calvinists). So that's 70% Lutheran, 20% Reformed, and 10% RC.
My spouse's ancestors were more varied: on one side, 6 ancestors were Jewish, one was a Jewish-to-Reformed convert, 3 were Reformed, 2 were Unitarians, 2 were Roman Catholics, and one (my father-in-law) was born and baptised Reformed but was actually a very devout atheist. On the other side, there were 7 Lutherans, 6 Roman Catholics, and 2 Jewish-to-Catholic converts. So that's 33% RC, 23% Lutheran, 20% Jewish, 13% Reformed, and 10% other.
Oh, and all 60 people were born in what was then Hungary.
