Well the names fit pretty well but I don't think we are on the same generations. My Frederick Redwood and Sophia Thorpe had 3 sons named Frederick (posibly Freddy), George and Henry (possibly Harry) but the birth dates are respectively 1838, 1846 and 1848. However there is still hope as Henry b1848 married Harriet James and 1 of their 10 children was a Henry b1872 of whom I have no further details. Brings a possible Harry into a more appropriate time frame but still maybe a little early depending of course on your own age. Do you have any dates and locations for your George, Harry and Freddy? If you do not wish to post these dates publicly then feel free to send e-mail direct.
Please let me know either way if this is helpful or not.
