Robb857,
Go to your ward clerk. Ask for your membership sheet to get your membership number. Take the number and go to new.family search.org and set up your account. Put in any of those relatives into the search window. When get to next page, choose that person, if more than one person with name, choose based on any data you have. Click on go to, which is blue box on extreme left. This will bring up the tree with the family name you choose. Scroll down until you see a column of grey buttons, choose second item. Next page pop up, look on right hand side any line item about that person, you will see who submitted the information. Click on the submitter name should provde contact information about that submitter. Beware, there are times when it was submitted from Salt Lake or multiple submitters. In that event, this was done by someone with the calling of an extractor. This means that they research courthouses, census records, ect and report this data to Salt lake and from that it becomes a temple name to have the ordinances performed. Hope this helps. This information comes from my wife who is a family history specialist.
