@longroad I grew up seeing both sides an equal amount, but my immediately family usually calls me by my first name unless we are around Spanish speaking family. My English speaking aunt also married a Spanish speaking person though, so if I were being introduced to someone in Spanish at their house I would be introduced by my middle name. For a while in middle school I also went exclusively by my middle name because my first name is a top 10 name
but my middle name has a cute diminutive so sometimes it’s used affectionately the way you might call your adult child a babyish name just because it’s cute.
My husband is in a similar situation as me (only his middle name works in his heritage language) but he did not have as much contact with family who speaks that language. However, when he visited the country though, everyone calls him by his middle name, and without Facebook they probably wouldn’t know his first/English name.
For our kid we gave her a first name that works in both Spanish/English and has almost identical pronunciations and a middle name in his family’s language. We use her first and middle name any time it needs to be written out (ie: birth announcement, monthly photos, etc) and weirdly my parents call her exclusively by her middle name which is NOT either of their languages. My brother’s wife is bilingual and she refers to my daughter by the slightly different Spanish pronunciation while my brother and I usually say the English one.
