Although the Occp Servant is down as Fathers Occp it is more likely Harriets Occp as I have seen this on many records of illegitimate Children.
Its strange as I just entered Wilkinson Dent on Familysearch, any England (no dates) and heaps came up.
The name Wilkinson was used often as a second name for many Dents born all over England.
There is a Wilkinson Dent Christened Westmorland 1800.
Joseph/Ann Dent, Harriets Parents name a Child Newark in 1802 so the Family likes unusual christian names!
Now I did notice this though;
Thomas WILKINSON Married Charlotte HALL, 10 July 1828, St Bartholomew, Keelby
Both Single
1841 Census
Keelby, Lincs
HO107/638/11/Keelby
Thomas Wilkinson, 40, Shoemaker
Charlotte Wilkinson, 30
William Wilkinson, 10
George Wilkinson, 8
Thomas Wilkinson, 6
All down as born in County
1851 Census
Keelby, Lincs
HO107/2114/24/19
Thomas Wilkinson, 49, Head, Mar, Cordwainer (Shoemaker), born Brocklesby, Sussex
Charlotte Wilkinson, 40, Wife, Mar
Geoe Wilkinson, 18, Son, Unm, Cordwainer
Thos Wilkinson, 16, Son, Unm, Cordwainer
Oliver Wilkinson, 5, Son, Scholar
All but Thomas born Keelby
So did Harriet have the local Shoemakers Baby?
Or is the Wilkinson christian name a red herring?
Gosh Thomas/Charlotte has 12 Children 1829-1848. Sadly most of them died. Two of them 8 days apart 1840 age 4 and 2.

EDIT , looks like 14 Children up til 1851 !
