Hi, I've attached the marriage.
Hope you can see it.
Thank you so much, ive now added all the information shown on the Marriage Certificate.
Can't make out the name of the Church... Its certainly looks like
St. Savior's, Parish of St. Pancras.
So we can see that Maria might have married twice.
That she used the surname Hablen, the father of her children when she married Samuel Henry Collins.
