For Sommerlatte there are 9 on Yasni with different names.
Among the most common last names on Yasni Sommerlatte is on position 4518.
It could be a double name with orthographically "eingedeuschtem" second part, ie summer latte, while the second part would then originally "lato", and that is to polish the same as the first part, namely the summer. A little support for this conjecture: The name is common in the eastern parts of Germany than in West.
