Identifying weeds in early Spring

These are just a few for starters.  Will be adding pictures as I spot more.

we all know by now the wild onion weeds, dandelion and chickweed so I refrained from taking those pics.

I know the first two pictures are a thistle plant, but of the weed variety.

 

These other ones from past experience I know are an unwelcome guests.

Pretty sure if you look close in above picture, that white flowering small leaf plant is chickweed, if not, pull it out as well if its in your garden.
