What a pleasant surprise to read your post.
I have not looked for information on Benjamin Rowe and his wife Susanna Kaiser for many years.
I only came across your post because I was trying to look for some information for one of Charles Henry/Henry Charles Pollington's descendants who lives in Missaukee County, Michigan.
I am the wife of Leroy Good who is a grandson of Malinda Angeline Rowe and William Harvey Good. Malinda Angeline Rowe was the daughter of Benjamin Rowe and Susanna Kaiser. My husband and I live in Ogemaw County, Michigan where Malinda and William Harvey Good last lived.
My records show that Susanna Kaiser Rowe died on April 22, 1921 in the Detroit, Michigan area. She was living at the time with her daughter Amanda (Mandy) Rowe Hyatt. I have a copy of the death certificate from Wayne County, Michigan, and a copy of an obituary from "The McBain Chronicle" of McBain, Michigan.
The obituary states, in part, that "Susanna Kiser was born in Dewerham, Germany, February 24, 1842, came to this country with her parents at the age of 13 years. She was married to Benjamin Rowe of Logan, Canada, July 3rd, 1862, 10 children were born to them. Six of whom survive."
Note: I believe Susanna's obituary should have read "went to Canada with her parents at the age of 13 years". I base that on the 1900 Census.
I only have the names of the six children who were named in the obituary, plus the name of one foster daughter.
1. John H. Rowe whose wife may have been Zella, maiden name unknown
2. Lillian Rowe who married Charles Henry/Henry Charles Pollington
3. Frederick Rowe whose wife was Mary, maiden name possibly Rowe
4. Malinda Angeline Rowe who married William Harvey Good
5. Jemima Rowe who married Lincoln Hess
6. Amanda Rowe who married Dave Hyatt
> Foster daughter, Mae Stearns who married Howard Hull
The 1900 Census of Riverside Township, Missaukee County, Michigan shows that Susanna had ten children with only six surviving at that time. That Census also shows that Benjamin Rowe was a Naturalized Citizen and that both he and his wife had been in the U. S. for 23 years. The year of immigration to the U. S. was listed as 1876 for both of them. You mentioned the 1900 Census in your post so I assume you already know this information.
I have a photo of some of the tombstones in Riverside Cemetery located in Riverside Township, Missaukee County, Michigan. One photo is the Rowe tombstone and another is the tombstone for Charles H. and Lillie Pollington. They can be scanned in my computer and e-mailed to you, if you are interested.
I would appreciate copies of the documents you wrote about in your post.
Because of time restraints and other obligations I will not be able to give you much more information than what is written here.
It might be easier if you contact me direct. My e-mail address is: firstname.lastname@example.org
