New Jersey 1915 state census

[Erato]

Can someone take a look at the image for this household:

New Brunswick, 5 ward, 5 district, Middlesex, New Jersey, United States
   
Julia Messerole       F       New York
James Sheehan       M       New Jersey
Margaret Cohan       F       New Jersey
Alex Mihalysko       M       Hungary

How old is Margaret Cohan and what is the relationship among these individuals?

I don't think the images are available online for that year.

Thanks, shellyesq.  Oh, well, foiled again.
