I have a rather extensive family tree on the above couple (Frances was my great aunt) on down. Here is what I have:

Frank (b around 1876-1880 and d 7/25/1934) was the son of Mikotaj Ostrowski (b 1821) and Josephine Wesolowski (b 1845).

Frances (b 7/30/1887 and d 2/11/1968) was the daughter of Tomas Piotrowski (b 12/19/1860 and d 12/10/1939) and MaryAnne Sniegowski (b 3/21/1862 and d 4/8/1944).

If anyone would like more information on this family or descendents, please respond via the message board...as others may also benefit.

Thanks!
