John, are you out there? Sent you an email, but didn't here back. I think you are right that this is Gaius' Mother Sarah. I believe Margaret Branch is one of the three older Croom children referenced in the 1840 census, but gone by 1850. I am not sure where you got the House maiden name for her, however, and would love to know. I found reference to a Joseph House of Greene County, with a daughter named Sarah whom married a Croom, but it seems she died twenty years before this Sarah. Hope you are well, and see this post.
