You are my cousin although I only know some of the names you mentioned.My Great-Grandparents are John P. Thacker (ca 1833 - 1923) and Lucinda Jane Coyle (ca 1837- ca 1887).About 1890 John's second marriage was to Ivy Marshall ca 1870 - 1934.
They are found in the 1900 Lewis County KY with children Melvin Bn 1891 Allen V. Bn 1893 Clarena (Clara) B. Bn 1898
The 1910 Lewis County KY census adds Florence Bn ca 1901 Ottie Bn ca 1904 Lora Bn ca 1907
The 1920 Fleming County Ky Census adds Walter Bn ca 1912
John apparently died in my Grandmother's house in 1923.
Ivy is still in Fleming County in the 1930 census.She died in Fleming County in 1834.I know virtually nothing about what happened to their children.
If you want to contact me we can share notes and both learn more about the family.
