I'm also researching the Rhone family name. The names I have from your grand fathers parents generation are as follows ( all have the last name Rhone ). Mary ann,1885-? Charlotte 1889-? Charles samuel 1892-? Mustgrove 1894-? Cathryn 1896-? Walter George 1899-? William nye 1904-1977. These are great grand children of James Rhone 1793-1854 married to a elizabeth? 1798-1858. I'm not sure if this is your line and I do wish you luck.
