Thank you for your reply. I can tell you that Elizabeth Linder was born about 1852 in New York City and died about 1898 in San Francisco, though I am certain she was in contact with your great grandmother Mary. I do know that my own great grandmother Elizabeth Wannamaker had kept in touch with the Schmitz family who lived in San Francisco. (My great, great grandmother Katherine Linder would be the elder aunt of Anton Gluckler Schmitz).
My great grandmother would be of course a first cousin to Anton Gluckler Schmitz so Anton Gluckler Schmitz is a mutual cousin to us both (a Gluckler cousin to yourself and a Linder cousin to myself). The children of Elizabeth Linder's second marriage to Wilhelm L. Schmitz would be half brothers and half sisters to Anton Gluckler Schmitz.
I do believe I came across the New York City death index listing for Anton Gluckler whom I can see passed away not that long after the son Anton Gluckler Schmitz (born 23 Oct 1871, New York City) Elizabeth's second marriage to Wilhelm Schmitz took place on 04 Oct 1874 in New York City. By the 1880 Census the Schmitz family were living in Oregon, and at some point I believe in the 1880s, they came to be at San Francisco. There seems to be a remote possibility that the Schmitz family were somehow related to Eugene Schmitz who was the mayor of San Francisco during the earthquake.
The Schmitz family were piano manufacturers and Anton Gluckler Schmitz was a piano tuner by profession.
If you contact me directly via my profile, I can then give you my direct email address. I can then send over to you various records that I have spotted in regard to Anton Gluckler Schmitz such as census records, his obituary, etc.
I'm sorry to say that I do not have any photos of Anton or his mother Elizabeth. I do have photos of his grandparents (my 3rd great grandparents) Martin Linder and Jacobine Kennel which I could share with you if you are interested.
Looking forward to speaking with you more on our Gluckler-Linder connections!
