I agree with the OP.
We know Carver (possibly Hawke) was at Ostigar. After Ostigar he fled to Lothering and joined with his family, and then they headed north.
The Warden was injured, had to heal, and then set off from a place that's further away from Lothering than Ostigar was. By all accounts, the Hawke family should be fleeing from Lothering before the Warden leaves it.
Moreover, you can visit Lothering after leaving it, as long as you don't finish your first quest. It wasn't destroyed *immediately* after you left.
In order for the Hawke family to head north from Lothering through Blightlands, it would have had to already have been taken. Did they sit around while the city was sacked and then leave after the darkspawn had corrupted the land?
Now, there are some easy ways to accommodate this extra time. Maybe Carver (and Hawke) got lost in the Wilds and the family waited for him in hopes he'd be among the stragglers.
1) The Hawke family escaped the destruction of Lothering. You se the smoke from it. The Chantry and the Templars had already left some time ago. This puts it after the Warden has left Lothering and during the Wardens first allied mission.
2) The Hawke family escaped south, not north, and somehow came behind the main hord. My guess is that their home was south of Lothering and they could not go north because that was where the hord was going. With the Imperial Highway to the left this puts them towards the Southron Hills. The prologue ends in the outskirts of the Wilds.
3. The Hawke family where trying to get to Gwaren wich lies southeast of Lothering.
4. Some stayed at Ostagar trying to help. Wynne had just returned to the Tower when the trubble started. And Carver probobly had to flee through the forrest witch takes some time. But who knows that they left directly that he (and Hawke) returned. Maybe their mother refused to leave untill it was almost too late.
