Hi! Do you think the farms - particularly GF - had any photo ID of the kids? When Ray takes a picture of Norman and Emma, they both say it’s their first time seeing a camera so it seems unlikely but the intro pages of the manga show the kids with a photo and other official identifiers.
If you wanted to, you could finagle a scenario where Grace Field incorporates photographs of the kids into management's records fairly easily, whether the kids are aware of it like in the live action movie canon or not.
But we're not shown any photographs of the kids when Isabella presents Krone with the children's files in the anime or the manga, nor when Krone combs through what's presumably a dossier she brought from headquarters to confirm the veracity of Ray's bait note.

This adds on to the tragedy of the cattle children being hidden away in this gilded cage from the rest of humanity, thousands lost to history over the centuries, as well as another minute layer of separation for the older ones where they don't readily have access to pictures of themselves when they were younger, how they weren't afforded the chance to preserve those bits of their personal histories while their peers in the human world do such things without a second thought. I've also mused about whether the only photographs they had of Isabella, their birth mothers, and their older sisters were ones taken at headquarters upon becoming a sister candidate here.
How surreal it is to see her like that, grappling with memories of the complicated woman they knew—the good and the bad—and the young girl staring back at them who resolutely held her head up high to prove she had what it took to survive in a demon's world, knowing all the unspoken pain behind her eyes.
As for the other premium farms, the mystic code book confirms they had greater access to technology.
(Mystic Code Book Chapter 3 Q&A; Goodwill Ridge isn't specified, but I'm assuming this is more so due to Shirai forgetting this farm exists most of the time and this extends to them too)
And at some point before they left, all the Glory Bell escapees had their pictures taken because Peter marks off which escapees they knew for sure were dead in this chapter 173 flashback panel.
