HELP!!!!

After talking to my cousin Dan tonight on the phone I am asking for help, this is a plea. If anybody who glances over this has any information on the Parsons family who traveled from England to Salt Lake please, please let me know. It is a hope of ours to make as accurate record as possible about our family. The members are we are looking for are Walter Sylvanus (Sylvanus Walter), Lucy Parsons, George Charles, William Benjamin, Emily Parsons or Walter Franklin. Most of the people listed were born in Utah. I have searched various records but I am searching for the fate of Walter and Lucy in Salt Lake or anywhere else they may have been. Any help in this matter will be good help. Thanks.
