I do have a Maria/Mary, but she is accounted for and married a Richard Bean. Although the other info you described does not fit anything else I have, I am curious about the Location. Two of Phillipina's sisters - Elizabeth and Katherina were married in Ann Arbor. I am wondering what drew them there? Katherina married in 1878 to John McCleery and Eliz in 1874 to John Frederick Lucas.
