Manitoba Nomination Program Document for relationship proof

[devganvishal]

Hi,

My question is regarding the relation ship proof .Case is that i have an aunt in Canada and in her Passport only First Name of my Maternal Grandparents are written ,Whereas in my mother's passport both Name and Surname is written .Is this something to be worried of while proving the relationship status ?

P.S:Spelling of the name is same for both parent .
