Same name as cousin?

Is it weird to use the same name that my sister in law used? Her kiddo will be a year and half when ours are born. We are having twins and I just liked the name she used For one baby and can’t think of anything else. I liked the name before she used it and it is a common name. Only thinking of using the first name, not the middle name.

We live in different states but my mother in law is VERY involved in all the grandkids lives so she’d have 2 with the same name.

EDIT- this is my husbands half sister and we RARELY see them, maybe once a year. We don’t see them at any holidays. The grandkids are never all together. It’s mainly seeing them on Facebook and hearing about them from my MIL. My SIL is 11 years younger than my husband. Not sure if any of that changes opinions.
