Each to their own, it's a tool like any other.
I changed "Laura" to "Flora" per her birth registration and tombstone, I think either/both being more reliable than the census. I added "Laura" to the AKA field, not because she might have used it during her lifetime but because other researchers might mistakenly be looking for that name. I also added Walford to Aaron and Elizabeth's AKAs. Adding spelling variants to the AKA field can really help the matching software finding duplicates.
I wonder if Trench may be a nephew? He's unfortunately born just before the lost 1890 census so by the time of the 1910 he could be deceased or has moved away from home.
I searched Tucker County births between 1886 and 1890 and Flora is the only child I can find registered to Aaron and Elizabeth. No children registered to anyone with name Trench or similar, for that matter no child named Trench registered anywhere in WV during 1878-1898.
