No problem with my old iPad. Logged out of Ancestry and in again with no bother apart from the two factor authorisation which needed a code to be sent by email.

Ignoring the Topic Diversion.
My devices are all connected to the router wirelessly; two computers, tablet and phone (all Apple) an I do not recall ever, at lest not recently, having to use a Capcha with Ancestry. Browsers I use are Safari, Brave and Opera.
As no one else on here has reported a similar issue then it is more likely some change in your set up than something Ancestry have done.
So have you recently added a new device to your household, cleared your cache, added a VPN?

Some Anglican vicars carried on using Latin for a century or two after the Reformation but most did not. FindMyPast and Ancestry will both tend to recognise that the given name Guillielmus is the same as William so not usually an issue.
The Catholics I think do still carry on the practice of using Latin to show that they are educated above us hoy poloy.
If I remember right I actually located the marriage using the name Maria Tooly with variation of both given and surname.

Keep in mind that the OP Joes Soap was asking what happened to Louisa's parents after their marriage and the birth of the two known children. Joes Soap may already know all the details about their two known children.
Thomas and Anne may have emigrated and left the children behind but unlikely. I had an ancestor who went off to "America" leaving behind his wife and children but I doubt if both parents would go and leave children behind.
Maybe they both died of Cholera or they split up or he was transported to the antipodes?  If either Thomas' or Mary's parents left a Will it might solve the issue.
