Incorporation query

Hi CCI members,

I had reserved a name for a pvt company to be incorporated mentioning Mr.X & Mr.Y as directors and promoters. 

But it didnt workout with Mr.Y so Mr.Y is rolling out of this partnership & other person Mr.Z willing to join and he shall be the director.

Now can I use the same name reserved earlier for incorporating a company having Mr.X & Mr.Z as directors or Should I go for new name so that I may lose my brand name which is prefix in the name reserved earlier.

Can anybody help me in this regard. Thanking you in advance.

Regards

Santosh
