I did see that. I think I am going to try to get a copy of the will; just have to figure out a way as I'm here in the US and it costs a fortune to get a money order in Sterling. I also found the records for his brother and sister. I may as well get all of them to see if any of them had kids.
Backstory - I was told that two of Frederick's (Harry's dad) grandsons died in WWII and wanted to try to find them. But so far, it's not looking like he had any grandkids at all. Looks like his sister never married and can't find that his brother had kids either. Maybe the wills will shed some light on it!
