Is it wrong if I don't ant my SIL to use the same

I would not be upset about using the same person - My churches dean is marrying me and this is the second marriage that he has preformed for my family - part of the reason I chose him was because of the job he did on their wedding - I was blown away.

I will say you need to use WHO you are comfortable with and honestly copying is the highest form of flattery you do realize
