I do not know about Gertrude--this is the first I have heard about her. I go to the University of Georgia, so we have access to the entire Ancestry website. If there's information about people that you want, I will gladly help. I've been researching the family tree for quite some time. The Jacob line has been elusive. If anyone knows the link between this line of Jacobs (plural of "Jacob," not "Jacobs") to Naomi Jacob (English author), please let me know. I know there is a connection. Naomi Jacob and my great-grandmother Doris Jacob, were very good friends. I'm thinking they must have been second or third cousins. I don't know where the Jacob line comes from, but I have extensive research from Christina's family in Scotland.
