How to update details on your emigration list (General)

by rookancestrybest , United Kingdom, Tuesday, September 10, 2013, 18:46 (4093 days ago)

I put some details of a member of my family on your emigration list a while ago (Charles J Rook and his wife Ann Mary nee Addams) and I have noticed that at the time I didn't know which ship they set sail on. I need to update it as I have the details but don't know how to do it. When I find it in the search engine there seems to be no way to update it. Please tell me how to go about it. Thanks.
