A few days ago I found the most amazing resource for wills. Probably everyone who is a better genealogist than I knows about it but I'll post it anyway for those just starting out:

England and Wales Probate Calendar (list of wills......) 1858 to 1966 at https://search.ancestry.ca/search/db.aspx?dbid=1904

I found wills of various ancestors and kept wondering who the "Percy Milford" was who was frequently mentioned as executor. Turns out he had married a great-aunt so another link was added to the family tree!!
