Had a look through to see if the Foot name had been mistranscribed in the 51 and followed the 61,71,and still the same all through to the 81. Where yet again the daughter in this case takes their mothers name for the daughter.. This daughter married as a Foot so absolutley no mistakes here. There are no near misses even with the Forth surname and Ellen!!!!!!!

PS Looks like heywood scored a direct hit earlier with the BMD info.
Ellen Foot 2b 655 1873 Jul - Sep Quarter Portsea Island

so looks like in the 1871 they were not married in the census but said they were.
Thats it now
