Not terribly surprising. They just didn't put it in back then. The only way you'd have it is if someone retrofitted it later.

So, you obviously NEED some insulation...

The traditional method of dealing with this would be to make holes along the tops of the walls, between the studs, and blow cellulose insulation in to fill the walls. My older house (built 1929) has had that done and it holds the heat reasonably well. Whoever did it neglected to do the spaces in the exterior wall in the kitchen which has cabinets on it and we have very cold dishes in the wintertime. It's definitely effective.
>What to do with the ceiling insulation though? Recomendations?
The usual treatment is to blow cellulose insulation several inches deep in your attic. Cellulose insulation is a recycled material, so you may like it from an ecological perspective. What you buy commercially is treated so it's flame retardant. It's relatively inexpensive and provides a reasonable amount of insulation too. The places you buy it will frequently provide the equipment to blow it in for free when you purchase the material from them.
Your message kind of implies there isn't an attic access, or maybe
not an attic at all. If that's the case you may still be able to do that, but you'd probably install it differently. A lot of how you do it depends on how much demolition you want to do. Blow in takes the least amount of tear out and repair. If you wanted to put in something like XPS panels, you'd have to remove the ceiling entirely. Big job.
