Martin Winn's kids seem to have different mothers?

[Seelife]

Hi Folks, sorry to come with another Winn mystery so soon.
I have a Martin Winn, born 1844 in Birtley. He has a series of Census records that I can follow the family through time until he appears to pass in 1913. I have his marriage to a Mary Storey in 1864 with a source from FindMyPast, and this seems in order.
In the 1881 Census, Trimdon, Stockton from DRO,  this is the family :
    Martin Winn Head, Married Male 36 1845 Coal miner & beerhouse keeper Durham, England,
    Mary Winn Wife, Married Female 34 1847 - Ferry Hill, Durham, England,
    John Winn Son, Single Male 15 1866 Coal miner Framwellgate Moor, Durham, England,
    William Winn Son, Single Male 13 1868 Coal miner Framwellgate Moor, Durham, England,
    Annie Winn Daughter, Single Female 8 1873 Scholar Edmondsley, Durham, England,
    Martin Winn Son, Single Male 5 1876, Scholar Durham, England,
    Michael Winn Son, Single Male 4 1877, Trimdon, Durham, England,
    Thomas Winn Son, Single Male 2 1879, Trimdon, Durham, England,
    Elizabeth Winn Daughter, Single Female 0 1881, Trimdon, Durham, England.
    A further daughter Mary was born it appears in 1887 according to 1891 census

But the thing is, the first three children appear to have a mother with maiden name of Storey, that fits OK. But the remaining later children seem to have a mother with a maiden name of Forbus/Forbes.

I notice that there are some family trees that say Martin married twice, once to Mary Storey then to Mary Forbes and Mary-1 passed away. For the record, I dont trust them, dont rely on them and dont use them as sources as 95% of them have REALLY iffy sourcing.

But I am not sure whats going on here. Am I just mixing up MY sources to make the kids fit?
Or, is there a mystery with Mary Storey/Forbes?  I cannot find a marriage of Martin to Forbes and cannot find any Forbes with a likely marriage. Did Mary Storey have a mixed parentage?
Thanks for any thoughts on how to pick this apart or explain the inconsistency.

What is Mary’s father name on the marriage?

[heywood]

1861 Framwell Gate shows Mary Forbes, 14 yrs with parents Michael and Ann.

This fits with 1851 2391/558/28 and a marriage 1841 - Michael Forbes and Mary Parkinson.

However, although the other children have Parkinson as mother’s name, I can’t find a birth for Mary Forbes

There is quite a gap between the births of William, 1868  and Annie, 1873.
Have you checked for births/deaths between these years?

[heywood]

1865 John Winn, Durham mmn Forbes

1867 William Winn, Durham mmn Forbes

1875 Martin Winn, Chester ke Street mmn Forbes

Do you have these?

[heywood]

But the thing is, the first three children appear to have a mother with maiden name of Storey, that fits OK. But the remaining later children seem to have a mother with a maiden name of Forbus/Forbes.

Where do you have the Storey births?

[JenB]

I can't find the two oldest boys as a Winn/Storey birth you refer to.

I can only find John and William born in Durham R.D. mother's maiden surname Forbes.

Annie's birth should be registered in Chester le Street RD.
There are two:
Ann Winn, 1871, mmn Forber
Ann Winn 1872, mmn Story.

Where do you find John and William with mmn Storey?

[JenB]

Ann Winn, 1871, mmn Forber

She was born 2nd q. 1871. there is the burial of an Ann Winn of Edmondsley at Sacriston on 7th May 1871 aged 14 days, so that might be her.

The two older boys, John and William, both 'of Edmondsley' were baptised at Sacriston in 1867.
