Hi Willow
I think you may have made a mistake.
Andrew and Sussannah did have 2 children baptised 17.9.1813 but they were Ann and William
Their son James was baptised at the Wesleyan chapel in Pump st 2.4.1820 born 16.1.1820.Labourer of Pump st.
Their other children Sarah 3.2.1811 St Alban ,Thomas born 27.7.1815 and bapt 20.8.1815 also at the Wesleyan of St Helens .So it looks like William and Ann were twins.
William seems to have been buried age 4 mths of Pump St 3.1.1814.Thomas also died age 7 weeks buried St Andrews 13.9.1815,of Pump St.
That leaves Sarah ,Ann and James.
The couple married at St Johns 8.2.1807.
Susannah is buried at St Peters 7.3.1856 age 76 of Sidbury.
Andrew died Mary qtr 1867 born 1779.
1841 census Sidbury St
Andrew 60 ,Susannah 55 and James 20. I can't read the occupations.
Are these the people you are after?
