From the census work I did Lydia Margaret Rife was the daughter of William Granvill(e) Rife and Cosby (maiden name unknown). Although none of the records I found showed Cosby (mother) maiden name.....I did find their death/cemetery record so you will be able to order these documents which should show maiden name, with luck.
William Granvill Rife bn 03 July 1878 Buchanan Co, Virginia **info provided on his WW1 & WW2 Draft registration forms filed in Buchanan County, Virginia... ***not to be confused with the G.W. Rife aka Green W. Rife born 1 Mar 1874 and also living in Buchanan Co, Virginia. The census records are very important for this family group because there are numerous RIFE men born around the same time frame,in the same area, and they named their children the same names.It can be very confusing.
You will find parents & several siblings buried at: Rife Cemetery Slate Buchanan County, Virginia, USA **father is listed as W.G. on headstone**
Only found one person working this Rife family group on the public web posted TREEs.But it is a current one so the email address should still be good. Hopefully you will be able to share data. With the cemetery link I sent you, you now have more birth/death info than this tree does for this one family group. http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?op=GET&db=rodgersmac&id=I285http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?op=GET&db=rodgersmac&id=I285
This is probably her brother Bascom Rife death record.I am sending it over to you because you just never know on who death certificate the mother Cosby's maiden name will be listed on.
