Missing parents from census.

so Samuel married in Liverpool
then reappears in Bury where their son Isaac is baptised in June 1841

That's right - Samuel states he is from Helliwell and Mary is from Liverpool. Then they presumably move to Horwich. Whether this is the correct family though needs further evidence.

[lancsann]

just to complete the family, there is another Mary baptised 1825 who presumably dies

[Philezra]

Lancann. Where did you find the 1825 baptism?

All of you - a very big thank you for all you help.

There is a John Barrow in 1901 at an institution in Farnworth as a pauper/inmate.....

[lancsann]

On ancestry. hopefully of the right William and Alice.

[Philezra]

I actually thought, afterwards, that you were referring to Mary Barrow, daughter of Samuel + Mary, born 1825.

From what I can glean, the rest of them, John ecxepted, couls have died between 1851 and 1861; Samuel snr 1853; Mary 1851; Samuel jnr 1860 and Isaac 1858.....

1881 3832/79/6

Living in Sharples (Bolton)

John Barrow born Birkenhead, Cheshire with Mary, daughter Alice and three more children.

1891 3112/47/14
Still in Sharples

John - b Birkenhead now a widower with the three younger children - there ages are not correct though 

[heywood]

Now that it looks as though John Barrow is born Birkenhead, I would think that he is the (unmarried though) John boarding in Wallsend in 1861.

1861 3835/36/33

Birkenhead is transcribed as Burlouhead on one site.

[heywood]

Here is John's baptism in Birkenhead.
