I'm not entirely comfortable with the sarcastic use of "transgendered" here. In any case, please provide a source for the gender and I'll be happy to change it. "It's a masculine name" isn't good enough for me to change something another user put in, especially with so many cases of families ignoring gender-norming names over the centuries. You know by now that we ask for citations for everything when making changes in order to be certain and to make sure errors don't happen again in the future. So once you provide one, I'll edit.
I've seen a lot of oddball naming, but not with "Silvanus". That one would be a REAL first. Silvanus/Sylvanus was an old Roman god - not goddess - of the woodlands. (And people in the 18th and early 19th centuries used to know things like that.)
I haven't *ever* seen it used as a woman's first name, and I don't ever expect to. The female equivalent would be "Sylvia".
What's equally to the point is that I haven't found any documentation whatsoever for anyone named "Silvanus" - male OR female - as a son OR daughter of Mary Wade Justice.
And I *have* found *lots* of evidence that the Justice family lines (plural - there were at least two, one out of Massachusetts and one out of Virginia) have gotten totally snarled up due to bad/no research.
See other post, re Mary Moore Justice.
I've been tracking the Eastern Virginia Justice family via the Miles Files, and it's perfectly clear that none of them had anything to do with Massachusetts.
But, somehow, people keep jamming the Massachusetts Justices and the Virginia Justices together and then jumping through all kinds of hoops trying to explain the discrepancies.
