I found Susanna's obituary on a research trip to Manistee, Michigan. I visited the local library and looked up obituaries and found hers. Although, the obituary is short there is enough information to know that this is the Susanna Fredrich I am researching. There are a couple of mistakes in this obituary. One, Mrs. Radtke is a granddaughter. Secondly, Oak Grove Cemetery, in Manistee, has no record of her burial there.
The people mentioned in the obituary are: Mrs. August Guhse is Susanna's daughter, Ottillie. Mrs. Engelhuber is her daughter, Amalia. Mrs. John Zobel is Susanna's daughter, Henriette. Mrs. Radtke, is Susanna's granddaughter. The one son would be my great grandfather, Johann August Fredrick.
The obituary and transcription are below.
