My name is Teresa Pyne and I Joseph Coffield is my grgrgrgrandfather. I descend from Betty Jarvis who's mother was Alice Jane Muckey who's father was Stratton Franklin Coffiled who's father was william Oren Coffield and he was the son of Joseph N and Lydia Jane Johnson Coffield.
I too am researching the Coffield line and so far I haven't been able to get beyond Joseph, but I am hoping to get some more information on his father from his Civial war Pension File when it gets here.
I do show Joseph & Lydia together in the 1850, 1860, & 1870 Federal Census, also the 1852 and & 1856 Iowa Census. I found Lydia in the 1880 Census but no Joseph.I also found Lydia in the Denver directory in 1892, and in California in 1900 and 1910 Census living with her daugthers.
I found out that Joseph diedin Colorado Springs, El Paso, Colroado on 9 Feb 1899, but not where he is buried. I have no idea when or where Lydia died (still searching).
Any info that you have would be great and I hope what info I have helps you alittle more.
