Six of the seven sons of John Dake, Jr. and Catharine (Bowman) Dake

#1   - John Jackson Dake (b. 1819 in Virginia - d. March 30, 1896) Lived in Shelby Co., IN, Clarke Co., IA, Wright Co., MO
#2   - George Washington Dake (b. 1833 in Indiana - d. 1893)
#3   - Possibly Frederick Dake (b. 1826 d.1913)
#4   - Possibly William Dake (b. 1828 d. 1909)
#5   - Benjamin J. Dake (b. 1821 in Virginia - d.1908 in Shelby Co., IN)
#6   - Daniel Dake (b.1818 in Virginia - d.1897 in Shelby Co., IN)

Date and place of photo are unknown but #2 died in January of 1893 so it would have to be prior to that date.
Note that there is some dispute as to which are Frederick and William.  Other confirming photos are needed to be sure.

#7  - Henry Dake (b. circa 1832 - d. March 17, 1965, shortly after returning from the Civil War)
