estimated 1891. Children Joohn(b.1878), George(b. 1880),Isabella (b. 1882) and Donald(b. 1885)listed on 1900 US census. 5th Child was Barbara. She would have been married by 1900. Can't find her. Any ideas where to look? 8 Jan 2011-Found her! She was in NY State Census living with mother-in-law. Sometimes searchs use first initial and middle name. That's how I found her husband.
