Schneider, Robinson, Perry's Albion and/or Lowell Mi

I have recently come across photos of a Charles "Guy" Perry and Eena Francis Perry that were taken professionally in Lowell Mi in what looks to be the late 1800's. I have found cemetary records that tell me he was about 7 years older than her, and her real name was Eunice, but the names were handwritten on back and I have no idea if they were siblings or married. The ceme ary records list her parents as Henrietta Walker and George Robinson, I have also found pictures of Henrietta Walker Robinson with a Julietta (Robinson) Schneider and Lena (Schneider) Lane, and an infant, George Wm Robinson that were taken in Albion (the photos are beautiful and considering the era it's obvious they were wealthy), I'm assumihg they are all maternal relatives, but so far can't figure out how any of them tie into my grandma's family, which was the Roth family from Lowell, Mi. If anyone can help, please let me know!
