I think Sir Edward was briefly High Sherrif of Norfolk and son of Jacob Astley the royalist general, but it’s tricky to work out from the info available via google. The painter is anonymous and the picture hangs in the National Trust collection at Seaton Delaval in Northumberland. Sir Edward is wearing what looks like a pinked satin doublet with a falling band decorated with wide lace that is also used on his cuffs. He’s also wearing a nice wide, either embroidered or embossed sword baldrick.
