 They are on the 1900 Census in Cleveland with Mary's sister Eliza Brown, single. Mary is born Nov 1845 and Eliza is born Mar 1855. They are both born Ohio, father born Massachusetts, mother born Pennsylvania.

Adam dies Dec 27, 1901 in Akron, Ohio and is buried with his first wife Sarah Milliken in Oakwood Cemetery, Warren, Howland Township, Trumbull Co., Ohio.
Mary died Aug 23, 1908 in  Cleveland. Her death record does not name parents. I don't know when Eliza died. At first, I thought it was her on Nov 26,1907 but it is not her. I have tried for years to find the parents of Mary  M. and Eliza. I have looked at the 1860 census trying to find them together in Ohio. I have tried to find Mary's first marriage to Mr. Raymond. I have searched trees on familysearch and ancestry. I have phoned Woodland Cemetery where Mary is buried. I just can't sort this family out.
Can anyone help with this? Thank you. Peggy

Just a gentle reminder to use RootsChat's URL shrinker when posting that extremely long link.
https://www.rootschat.com/links/

Also, if you post an Ancestry etc link like that, only people who have an Ancestry subscription will be able to help you. For Ancestry non-users, that link opens at the subscription page.

Much better to post a snip from the page using, for example, the Windows snipping tool. Attach the image using the “Attachments and other options” box.
