I am searching for information on an Irish immigrant named William P Crowe. I do not know exactly where from Ireland he originated, but from what I've learned, he was born in May 1850. He immigrated to the United States in 1868. According to the Chicago Voting Records of 1892, he came to Chicago right after he immigrated. He married a woman named Hannah, an immigrant from Norway. She was born in Mar 1861. She immigrated to the United States around 1878. I am very certain they married in Chicago, but I am not sure of the approximate date, but based on the Census records, the year of marriage is estimated to be around the year 1881.

I was wondering if it is possible to find their marriage certificate. If it is possible to find the certificate, I would love to see it.
