I think a longer middle name flows best with both [name_f]Tess[/name_f] and [name_f]Nell[/name_f] since they are on the shorter side. If you are finding it hard to find a middle for [name_f]Tess[/name_f] maybe you could consider [name_f]Tessa[/name_f] or [name_f]Theresa[/name_f]/[name_f]Therese[/name_f] with the nickname [name_f]Tess[/name_f]. Same goes with [name_f]Eleanor[/name_f] or [name_f]Helen[/name_f]/[name_f]Helena[/name_f] for [name_f]Nell[/name_f]. [name_f]Hope[/name_f] this helps
