As mentioned elsewhere in this forum, Mathilda was married to Charles P. Nevin, a prominent Montana businessman born in Virginia City, NV in 1881 and died in Butte MT in November 1936. I can find nothing on Mathilda after the 1930 Butte MT Census. I cannot match up a death record to her. Mathilda O'Malley was my great-grandfather's niece (Michael Patrick Lavelle). She was born in 1884 in Wisner, Nebraska near as I can tell. Michael's parents, several siblings including Mathilda's mother, Bridget Lavelle O'Malley, were trekking west from Scranton PA to Butte MT. According to the 1880 Census, they were in Wisner NE. So, if anyone has any information on Mathilda O'Malley Nevin, please contact me. Thank you!
