Hi, I'm descended from John Etling's brother George.
(my source uses 2 t's in Etling)
The line that I have is as follows;
George Etling m. Anna Moritz
(sons John & GEORGE ETLING)
George ETLING m. Mary Louise Kamman
daughter Ellen Louise ETLING m. George Kiehl
son Henry John Alexander KIEHL m. Ida Mae McAlpine
daughter Margaret Isabel m. Archibald D. POLLOCK
son Douglas F. POLLOCK (me)
I have a 4 page letter written in 1959 that details this all this & can email scanned copy if it would be of assistance.
