can they be regardes near-synonyms in this context?

No, they are not synonymous--but the two words you have bold-faced refer to a man's children. Words do not become synonyms just because someone uses them creatively to refer to the same thing.

Where did you find what you have quoted? It was either badly written in a poor attempt to mimic an archaic style, or it is a passage of archaic English which has been copied in a faulty manner.

it is from bacon
it is from francis bacon's Of Marriage and Single Life


i just want to know whether they could be regarded as near synonyms in such a context.... where both of them refer to wife and children??

thank u

In the context of how the terms are used, the meaning is synonymous--but that does not make those words synonyms, and they are not.

If the passage is from Bacon, it has been badly copied.

thanks for ur help
