I am no expert but I would have thought that the inclusion of another given name and the change to the surname could have been the decision of the person themselves.
1) A marriage ceremony is one instance where the parties can legally change their surnames without extra costs, This was the case when my son-in-law married my daughter and changed his surname to our family surname simply because he didn't like his own surname. You also find change of surname occurs when a man marries into a family where the bride is an heiress to a farm for instance and the terms for the inheritors of the farm should always be known by that surname.
2) I have an EV. Lutheran g. grandfather baptised on the European mainland in 1854. He was named in favour of his grandfather Heinrich who was present at the baptism. When I approached the Ev. Lutheran church archives for details of Heinrich the grandfather I was given the names of his wife and their several children; the children had all been baptised in the local village Lutheran church. This wife was not the grandmother of my ancestor. Additionally I was informed that the wife and children were Catholics, and I was referred to the Catholic archives for more details. From the Catholic archivist I learnt that all the children had been given a Catholic baptism on the same day in Hildesheim (the oldest being 10 yrs of age) and when comparing the Ev. Lutheran record of the family's names with that of the Catholic record of names, the lists were identical. The Catholic archivist informed me that where there was no Catholic church in the near vicinity where the father worked, then the family were allowed to attend the local parish Lutheran church.
3) I do have an anecdote from the 1960s when my late husband was seconded to the NATO forces in the Netherlands. Single men lived on the campus but married personnel were dotted around living in apartment blocks in the near vicinity. One early evening a co-worker of my OH walked into our flat rather disconsolately and asked for a favour. He explained his wife was a Catholic and when they'd married they'd promised to rear any children as Catholics. He explained this wasn't a problem but what he took umbrage at was that when the Priest made his weekly afternoon visit, his wife offered him a glass of whisky and this particular day the co-worker had arrived home tired and sweaty needing a shower and then relax with a glass of whisky, only to find the priest had emptied the bottle - so could my OH offer him a drink?
