We could try to look for her userame @claudedlm, but it will be only useful for the next part.

Nope, for this one, only google the words of the documentary: documentaire 2010 esclaves ile

The first links talks about ‘Les esclaves oubliés de Tromelin’, a 2010 documentary about slaves on an island.

Social networks

It’s time for Social Intelligence. In her email, claude has written her @claudelm. Just try a tool like WhatsMyName for username lookups. We then find her Mastodon account: here

Her very first post confirms that we are on the good person (about old documents). The next post is what we need to find her son:

This post teaches us that:

• Her name is “De La Mergerie”
• Actually, she divorced recently, and the name of her ex-husband is “Vainsseau des taies”.

Now that we have her ex-lastname, we can search for it on… Facebook for example?

Bingo, her profile

Here is Gabriel, her son, that liked the picture and gives us directly his profile.

There is this post about a city and a sold house:

He talks about a trip he did in the city with the castle, that near this pylon there is a pharmacy in front of a residential area, across a large road, where he saw a house being sold.

1. Where is this castle ? -> Google Lens: King’s Castle, Limerick, Ireland
2. Where is that pylon? -> Kinda hard part. Much easier to take all four elements all at once (pylon, pharmacy, large road and residential area)

I was searching for those elements:

• green corner with sidewalk: still in the city but not the center
• orange brick wall
• Trees
• semi-big pylon

By wandering on street view, this is the only zone that approximately matched, and I was able to find the same type of pylon on the edge of the city.

Then I found that this zone could match: pharmacy, residential area across the large road. This gotta be in Coolraine Heights

By searching coolraine heights sold house on Google, this site looked promising. We were looking for a house sold between 25/02/2023 and 05/03/2023.

We got our matching house!

Another search with the address will easily give us the area: 111 m²
