Check with the amphur, but the Thai translation of your name might not be needed if you have these already on another offical Thai document, such as marriage registration or maybe even Thai driving License or work permit.

My amphur was happy to copy these details from my entry into the Thai marriage register. It also makes surre that I am registred with the Thai government under one and the same name.

Can only confirm that.

I you are legally married (registered in Thailand) you have the transciption of your name in Thai and usually your wife has an ID card with your last name in Thai.

The official rules for transcription from Roman to Thai are quite complex and only professionals know them.

As far as I know, there is no SW for it available.

So if some official tries on his own you will likely have a different outcome.

(for the other direction from Thai to Roman there is SW and websites for the task).

Name of father and mother are required. Its simply the standard procedure as required for registering a new born Thai.

Your registration is somewhat similar, as you are assigned the unique person ID like any Thai has and keeps for the rest of his life (13 or 14 digit number, I forgot).

This number makes it easier for all government offices and others to "handle" you.

They type in the number and they have your file (much easier than searching for a farang name).

I made the first fruitful use of my yellow tabien baan the day before I flew home to Italy. At the Silom Complex (191 Silom Road) in Bangkok I stopped by the Siam Commercial Bank branch (SCB) and asked to open a fixed deposit account to transfer into it the 500,000 Baht I hadn't spent during this visit to Thailand. Although my savings account was also with SCB, further down the road in United Centre Building (323 Silom Road) and I had may bank savings account book with me, this was not enough.

"Do you have a work permit?"

"No. Will the tabien baan do?"

The employee's face lit up. I didn't have it with me and she suggested I should email it to her. Luckily, I had a copy of it in Google Drive and emailed the relevant pages to her there and then. After signing half a dozen or more sheets of paper, I was out of there with my fixed deposit account book, money to earn good interest until my next trip to Thailand.

Most of the time, all you need is a copy of the tabieen baan and your I'd, and the world is your oyster.

Is it possible for a Thai person to be listen in two different ta bien baan concurrently? Say for example they have a house in the burbs but also rent a condo downtown because its close to work.

No, any person, Thai or foreigner, should be listed in only one house registration book. Officially, this register serves for the population census and for Thais is the place where they have the right to vote. If a person owns more than one house or condo, he will have a house registration book for each but his name will be listed in only one, ie the one he indicates to be his place of residence. I know Thais who have several blue house registration books for the various condos they own and have the name in none of them because they are still registered at the house of the parents or or another relative.

Has your family reported your living there to police/immigration?

Does the 90 day reporting process satisfy this? As a money-saving measure, my wife and I moved in with her son back in November. He has a decent size house anyway so it made sense. About a week later was my normal 90 day report, and I reported the new address at that time. Did that satisfy the "tell the police" part, or do I need to go somewhere special and tell them also?

I've not gotten my name added to the new house register (I assume it's the son's register) but I'm thinking that I'd like to be added but it sounds like such a circus. If I'm reading this thread right, it looks like all three of us (the son, wife, me) will need to go to the Amphur, along with one, possibly two witnesses from the village - correct?

Not only you ned to rerrot your address, but the housemaster (your wife's son) also needs to report your stay at his house. For private citizens it is currently not often enforced.
