When a conveyance of real estate is made by a married woman and such real estate was acquired by her under a name other than her present married name, such conveyance shall set forth both her present married name and the name under which such real estate was acquired. Such conveyance shall be indexed by a town or county clerk receiving the same for record under both her present married name and the name under which such real estate was acquired. However, a deed which fails to describe the grantor, as aforesaid, shall not impair the grantee's title conveyed by such deed.
