'servants'(Modern English swain)
Always derived from ON rather than the OE cognate because of the vocalism: cp. OIcel sveinn 'boy, young man, servant' < PGmc *swainaz (cp. OE swān 'herdsman, peasant', OS swēn 'herd, swine-herd', OHG swein 'servant, shepherd').
Proposed ON Etymon (OIcel representative)
