Dear Group,
This is a Yiddish sentence from a pre-WW2 postcard.
https://www.jewishgen.org/viewmate/viewmateview.asp?key=VM98482

The writer refers to three names of relatives in this sentence. 
I'd like whether their family relationships with the writer is implicit or explicitly implied in the text.
A precise translation will be highly appreciated.

Thank you!
Yaron Wolfsthal, Israel.
