hello Everyone, Finally back with some information.
First though I need to apologize to allanpeter and softly softly re Alfred William Gorringe. I thought he went with Emily but that seems to not have happened so I really do not know either way and all my documents have no reference to that. I have been trying to piece together the immigration to Canada and that seems to be complicated as Emily could have cone there and returned to England and then back to Canada. One document mentions a friend in California so I'm, still looking at this.
Now back to the three first children of James Monroe {?} and Elizabeth Taylor.
I have now got the birth record for Robert Henry Munroe :
DOB 15th November 1858
Place of birth : 14 George Street [this matches the address on the two boys Baptisms - jonw65]
Father: James MUNROE
Mother: Elizabeth Byzanter Munroe formerly Taylor.
Father Occupation: Woollen Manufacturer.
Informant is Elizabeth and she is at 14 George Street, South Hackney.
The registration was done on the 27th December 1858.
Emily was not born till the 25th June 1860 - so Robert and Emily were not twins.
I also got Elizabeth's Death Certificate 12th Dec. 1917. She was at 44 Hawley Square U.D.
Described as Widow of James Mornement,
Clerk in Wool Warehouse.Her Daughter Louisa Mornement [Turner] was the informant.
Okay i have the answer to my question with a few extras so thanks everyone for your assistance - really appreciate it.
