That Winifred looks a strong possibility (i hope)
Marriage Free BMD
Manchester 1860
Patrick McPortlane and Mary McMannelly (GRO has Winifred’s mother as MacNamee)
Lancashire BMD has Patrick McPartlane and Mary McMannelly - registrar or registrar attended.
Lancs OPC
Baptism: 13th April 1862, St Joseph, Ancoats, Lancashire
Winifrida McPatrond - filia Patritii McPatrond & Mariae (formerly McNameney)
Birth 6th April 1862
Godparents: Michael McPatlond; Anna McPatlond
There is also a baptism for William b 1869 (lancashire BMD - mother's name McNamah)
Lancashire bmd shows deaths in 1869 for William and also Mary McPartland 30 yrs.
This fits with the 1871 census where Patrick is a widow.
There is also a child Mary on that census but i can’t see a birth.
