Searching for info on above who married in Chicago in 1878.

Friedrich's occupation in Chicago was a gilder and he also had a brother Gustav who was a saloonkeeper and brewer.

Friedrich died in January 1889 and Gustav in (I believe) 1896.

Have been unable to find any info on Friedrich's wife Martha after his death.

If there is anyone out there this might sound familiar to, I'd really appreciate any clues as this has been a brick wall for a long time now.

Would really like to find out what happened to my great-aunt.
