Oliver Barton Griswold

I found another Griswold in my line.
Oliver Barton Griswold married Anna Lois Howe.She is the sister to Betsey Howe who married Hewitt Griswold.
Both girls were married in Newport, Sullivan County, New Hampshire.
Could they both married brothers, Oliver and Hewitt (if this is a Junior), the sons of Hewitt and Abigail Griswold?
