I have proposed the merge for you.
You can initiate a merge scrolling down all the way when in a profile's page.
To the left you'll find [Initiate a merge], after clicking on it you'll be asked the WikiTree ID of the other profile you want to propose the merge with. Then you can COMPARE side-by-side both profiles and decide to propose the merge.
You can practice with Robert (Matthew's father) and Matthew his son and namesake. They are also duplicates.
