Clearly state what information you are seeking (Announce)
When posting a query, tell us what you want to know
Otherwise the answer is just going to be a stab in the dark. Probably the worst thing you can say is "looking for any information on William Jones". What information? - Be specific
If you are trying to find when and where a person married or the name of the parents, then make it clear that you are seeking that information.
It is frustrating for a respondent to spend a lot of time gathering and posting information about a query, then the original questioner, replies with "I already have that information".
