Most of this information has come from the Sparks Quarterly via my nephew in Virginia.
Right now I have 2200+ on my Sparks tree as combined with my mother's side - Dean.
I have about 40 CD's (plus a Native American CD purchased locally) from Family Tree Maker and am still digging.
Will contact my nephew and see if he has anything more.
