Am I jumping to conclusions?

[vita]

Still relatively inexperienced, could I please have some advice on this one?

I know nothing at all about g/g/grandmother Ann Headland, nee Williams,

except that she died aged 28 in 1838 after the birth of her third child.

Her maiden name made me think it would be impossible to establish anything

at all about her, but I see an Ann Williams b 27th Aug 1810, baptised 21st Sep

1810,St George Hanover Square, London, father John & mother Susanna.

The area & date is right, & my Ann named her daughter Susanna - do you

think I might have found her or have I fallen into the "wishful thinking" trap?
