If you google daniel emmett married ann harrison there is a WikiTree for this couple.
(not a lot of info though)
https://www.wikitree.com/wiki/Emmett-569The Emmett surname is familiar as I worked on a George Emmett a few years ago (born Berkshire)
I had a quick search on Rootschat but cant see any queries about Daniel.
I did some searching and found;
FreeREG has Daniel/Anns childrens Bapts Thorpe, Surrey (bapt 1807-1825)
(+ burials of 4 of them)
I presume you know Ann Harrison bapt 2 Sons 1802/1805 in Thorpe.
Cant see a Marriage to Daniel though for her.
Gosh Daniel was a lot older than Ann;
Death Reg
EMMETT, DANIEL age 84
GRO Reference: 1850 M Quarter in WINDSOR UNION Volume 06 Page 201
1841 Daniel is not born in County (Surrey)
Anyhow I went off track, so good luck with your search
