Here are a few more obituaries; not sure if the first two are any connection to your FLICKs.
1935 death of Paulina (ZINKHAN) FLICK, first married to John ZINKHAN, second marriage to Christ FLICK. If this is your Christoph who died in 1940, he would have been married 4 times?
1955 death of Anne FLICK, no mention of husband's name.
1976 death of Frank ZACHMAN, predeceased by Elizabeth FLICK.
