Rebecca,
Hello ! I got your response to the ancestry message board posting.I tried to email you but got a damonmailer. I don't know if I can help or not. One of my GG Grandmothers' on my father's side of the family was Susan Frances { Eacho } Burch. She was the daughter of Achilles L. Eacho of Richmond, Virginia. Giving you dates for this family may be premature at this time . If not related to Achilles it would do you no good. Outside of what I have basically told you,I haven't done much on the family. I do have alittle info though.
You mentioned that your Grandfather was named William Henry Eacho. His father was Wm. H. Eacho Sr. Do you know who Seniors father was and when and where senior was born ? I do not have full access to the Ancestry.com Census records. I do have access to Heritage Quest Records. These are listed by head of household only.{1860-1930} I could try to look up something for you if you want. I do not make any guarantees though. If not, I can only suggest that you gather everything that you have together and write out a message and post it on Rootsweb or Ancestry. Both are the same. You might try Genealogy.com. I think Genealogy still has their free sign up thing so you can use their service. You just have to look for it.
Sorry I could not have been more help to you. If you do have any questions,just ask.
Wayne
