In 1930 Janet's parents were listed as born in PA and IN. According to the 1880 census, Geo. Fertich was b. IN but his parents were b. PA. I think Janet was Daisy's sister, b. ~1884 in Ohio (according to 1930 census).

1910, Battle Creek, MI
Can't find in 1920 or 1930. Deceased???
FYI: Walker is on Grand Rapids' northwest side.
I didn't answer your questions, but maybe something here will be of help. I did find something under Lickles. It's that curly-cue S/L similarity to watch for.
