Would love some help with this. I'm creating a wedding invitation card and am confused on how it should be written. The invitation is for my dinner reception. I'm the grandson of Mr. & Mrs. Grandparents and son of Mr. & Mrs. Parents.
"On behalf of the late Mr. & Mrs. Grandparents, Mr. & Mrs. Parents request the honour of your presence to the dinner reception of their beloved grandson"
should the text in bold be "grandson" or "son"?
