Those links didn't work for me, Parser. However, when I tried the corpora, I found that nearly all the examples of 'excuse(d) myself to' were followed by an infinitive, not a person, as in:
I excused myself to take the call.
'to' = 'in order to'

Teacher Fivejedjon,
(1) Thank you for your kind note.
(2) As you know, I am a computer illiterate.
(3) Google "Excuse me to."
(4) When the first page of results appears, click on the word
"more" in the menu on the left side of the page.
(5) When that comes on, click on "books."
(6) Then pages of book selections will appear, mostly fiction.
Many by good writers have
to + person.
Now I must excuse myself
to you and take care of some
personal business. Have a nice day, sir.
