I didn't see Loella in seekingmichigan.org but this is a work in progress so keep checking (unless of course our governor gives it the ax). I did find Nattie J Herweyer and Tressie Rumberger in the Gratiot Co Historical and Genealogy site. Go to
www.GCHGS.org, look under data and forms then index, put in your name for a search. All the info they have is on this index. Tressie was listed in the 1980-1985 funeral home book (not sure if as deceased or family member) and Nattie J was listed under Sumner Cemetery 1994. This is an index - it doesn't give you the information but tells you where to find it at the Society. The volunteers are very helpful if you can't make it there yourself. It is located in Ithaca, Gratiot Co, Michigan and open only on Tuesdays. Check out their website. Enjoy your search
