Hi David. It might instead be easier to do one or more of the following:
1) Spruce up Alexander’s profile ( https://www.wikitree.com/wiki/Wood-24439 for those who are reading this) and then post a G2G post about him. The most important things for this are pictures, lots of sources, and a nice/long bio.
2) Make profiles for his other children, siblings, grandchildren, great grandchildren, et cetera that you know of, since that will come up on search engines. Following the guidelines I said above in 1 would be helpful for this, but even just properly sourced profiles go a long way.
3) PM the profile manager for Brenda’s profile. I’m not entirely sure where you got the idea that she is related (Wood is a very common name) but if you have a hunch you may as well say something. Profile managers don’t get notified that their profile was put on G2G.
