Margaretha is a first name that appears in my family in Aalen Germany. (Baden-Wu:rtemberg)
There is a famous expression in genealogy "Hiding under a middle name." In German areas it was common to use a 'Rufnamme' or call name. We would see this as a middle name. However the practice in Germanic areas was to use the first name only in Church mattters especially baptismal certificates.
SO... Margaretha might be under a baptism name like Maria Margaretha Smith.
I discovered that my grandfather was baptized Heinrich Ludwig Hormann. He used the name Ludwig Hormann here in the USA. This was discovered by the pastor of an Evangelical (Lutheran) church in the town were he was baptised. (that was not the village where he was born.
That village was too small to have a parish.) The information was in the 'Familiabuchen' from the church.
