Translations for husband and wife in French

Here are paragraphs from public domain books translated:

“I have given some attention to this matter, and it is undoubtedly of importance. There can be no question that Stapleton had a confidant, though it is unlikely that he ever placed himself in his power by sharing all his plans with him. There was an old manservant at Merripit House, whose name was Anthony. His connection with the Stapletons can be traced for several years, as far back as the schoolmastering days, so that he must have been aware that his master and mistress were really husband and wife. This man has disappeared and has escaped from the country. It is suggestive that Anthony is not a common name in England, while Antonio is so in all Spanish or Spanish-American countries. The man, like Mrs. Stapleton herself, spoke good English, but with a curious lisping accent. I have myself seen this old man cross the Grimpen Mire by the path which Stapleton had marked out. It is very probable, therefore, that in the absence of his master it was he who cared for the hound, though he may never have known the purpose for which the beast was used.

— Je m’en suis préoccupé, répondit Holmes ; ce détail avait son importance. Il est hors de doute que Stapleton ait eu un confident ; mais je suis non moins certain qu’il a toujours évité avec soin de lui donner barre sur lui en lui confiant tous ses projets. « Un vieux domestique, nommé Anthony, vivait à Merripit house. Ses rapports avec Stapleton remontent à plusieurs années, à l’époque où la famille habitait le Yorkshire. Cet homme ne pouvait donc ignorer que son maître et sa maîtresse fussent mari et femme. Il a disparu du pays. Or Anthony n’est pas un nom aussi commun en Angleterre qu’Antonio en Espagne ou dans l’Amérique du Sud. De même que Mme Stapleton, il parlait couramment anglais, quoique avec un curieux grasseyement. Je l’ai aperçu plusieurs fois traversant la grande fondrière de Grimpen et suivant le chemin que Stapleton avait balisé : En l’absence de son maître, il prenait probablement soin du chien, sans soupçonner toutefois l’usage auquel on le destinait.
