You have a better chance of receiving a response to your roll call posting if you add the names of the families your are working on in the subject line. And yes the time period is helpful, especially if there is more than one with the same name. I know I delete all roll calls that do not have names in them. I do not have the time to waste reading them all. One list I belong to invites new subscribers to list who is of interest to them in a post right after they join the list. Perhaps this would be helpful here. The more detailed you query, the more likely you will receive a positive response. Margaret Margaret R.
