Her article in thepeerage simply states she married an unknown Dale.

Lady Harriet's dress is a superb example of a double neckline and the use of sheer material. Her neckline is framed by a band edged with small embroidered diamond shapes. The inner edge joins a sheer partlet section with an inverted raindrop-shaped double bertha. Her puffed sleeves are slashed to reveal more sheer fabric while close diaphanous sleeves ending in small flared muffs extend below. I can only imagine that any number of Renaissance Ladies would have longed to wear a partlet and ruff like this. Her sleeves are just full enough to allow her to wear bracelets under the closer sleeve.
