Oldest Photographs from One Side of the Family

I am helping my mother and aunt with a family tree project. Both of them have been collecting facts, stories, and photographs on and off for decades. We think these are some of the oldest photographs we have in the family.

Thought to be Bridget Healy Queeny Dillon, who came to the United States in early adulthood. She was married to Mr. (?) Queeny and had two daughters. After Mr. Queeny died, she married Patrick Edward Dillon. Together they had a son, Richard Joseph Dillon, born on August 6, 1853, pictured here. Bridget is my great-great-great grandmother. Guessing young Richard to be less than two years old, it would seem this photograph would be from the late 1850s. Is this possible? Likely? Is it a daguerreotype?

This is a photo of Catherine Weber. She is the mother of the first husband of my great-great grandmother, Clara Elizabeth Kraemer Otte (Gutting).
