My Pony OC couple Brighteyes and Scramble Patch, sharing a romantic moment.
The gentry optician and the mountaineering ranger have been a couple since Canterlot Academy, they got engaged soon after and married after an appropriate time span.
Whenever Patch is out on ranger duty, they communicate with messenger pidgeons from Brighteyes' dovecote. Their correspondence, while exquisitely worded, is quite cheesy. Peafowl has threatened to burn every letter that gets too kitschy - mostly because Patch's squealing while she reads them hurts his ears.
And I want to note that Brighteyes is the size of an average stallion - it's Scramble Patch who is a small, especially for an earth pony mare.
I don't have everything planned out for them yet, but they are going to have at least two foals, a pegasus filly, Patina Patch, and an earth filly, Lace Gloves (named so in honour of SP's [adoptive] mother and grandmother, Velvet Gloves and Foxgloves). Patina being a pegasus can come both from Brighteyes' grandmother, who was from a mixed tribes family, and most likely SP herself, since nopony knows who her biological parents are.
