Meuli: Abraham/Meuli Family Lineage

I could use some help with the picture above. I know Earle and Isabel Dresel Meuli are on the right, perhaps courting or newly married.  I'm wondering if the father is Johann Martin Meuli and mother is Augusta Abraham. I'm thinking the others are children, spouses, and the two in the middle are grandchildren. If anyone knows or has some guesses, I'd love to hear them.

My notes from AR and Judith Meuli's research indicate the following:  John Abraham's son Albert August Abraham 1826 - 1920 married Anna Kedrowski died in 1864. Albert married second wife Amalia Agnes Von Haak 1840 - 1920

Albert and Amalia's daughter Augusta Eva Abraham born 8/9/1874 in Meinkowo, West Prussia, died 11/24/1943 married Johann Martin Meuli born 7/4/1871 in Graunbunden, Switzlerland, died 7/31/1945 in Chippewa Falls, WI from Duodenal ulcer, senility, and atherosclerosis, married 6/12/1894 in Chippewa Falls, WI son of Johann Martin Meuli born 1813 married Maria Louis Cripolani 1826*

Augusta's siblings included August Herman Abraham (son to Anna Kedrowski) 1864 - 1943 married Bertha Emilie Ottilia Beyrer 1848 - 1936, Ortilla Bertha Abraham 1877 - 1965 married to Oscar Albert Krause 1870 - 1952, Karl Herman Abraham born 1868, Amanda August Abraham 1870 - 1941, and William Abraham 1880 - 1897

Augusta Abraham and Johann Martin Meuli's children included: Earnest Meuli 1895 - 1956, Agnes Louis Meuli 1898 - 2001, Earle Joseph Meuli born 9/27/1902 in Chippewa Falls, WI married Isabel Mildred Dresel daughter of Anna May McDougal and Frank Dresel.

Earle Meuli and Isabel Dresel's children included: Earle Joseph Meuli, Gerald Robert Meuli, Yvonne Isabelle Meuli, Judith Meuli, and Allan Richard Meuli
