Both sides come from ashkenazi Jewry (and a touch of irish/Swiss). Each side pining for their romanticized “old country”. Both sides grateful to be here and free from persecution ( well, mostly). There is so much confusion as to what the old country was. At this point , it seems like a dream- Gypsy violin playing, seders that meant something and were cherished. Ultimately, love lasts and the default culture is Jew. L’haim.
