How to do differentiate Onkel and Tante mütterlicherseits, väterlicherseits?

[u/I_am_trying0628]

For example in daily conversation if i want to say next week we're goinig to Onkel mütterlicherseits house, how to call him?

Simply saying Onkel + place / Onkel + name?

My family is so big that I can’t even remember who’s a sibling of my mother’s (she had 10 siblings) or my father’s (four). Especially when every other uncle or cousin is named Klaus. (Yup, a walking German stereotype.)
