OK. Well without finding Christian Jensen in that index, I would have no real way of finding that obituary since you don't have a firm death or burial date.
Unfortunately I struck out with Amelia Bronson Jensen. I checked the Omaha World Herald morning and evening editions from 12/25-30/1948. She wasn't listed in the obituaries section for any of those dates. I also struck out with Anton Bronson. I checked the Omaha World Herald morning edition from 01/18-23/1928 for him.
My only success is Julia Bronson Anderson. Her notice appeared in the 07/28/1934 Omaha World Herald morning edition on page 22. It's attached.
