Hi Tazzie
The entry was from the P.C. records so would be as correct as they can be.

No marriage in Rushden for Thomas and Frances although there is one in
Little Addington that may fit as Thomas is of Rushden and they had lots of childen
baptised in Rushden and only a couple of miles away.
I will find it in a moment.
We all know how badly the I.G.I. coverage of Northamptonshire is.

Other children of Owen's baptisms at Parish Church
Catharine d Owen mat maker &
Maria Palmer otp Feb 28 1830
Fanny d Owen mat maker & Mary Ann Palmer otp Nov 16 1834
Only the 3 it seems.
Cheers Sandy
