John's Father/Mother was an Ancient

[doomsdaybrnete.livejournal.com]

Just finished reading a story where Janus was John's father. It was a well done story, but the revelation of the identity of his actual father, and what was left to him by that father, wasn't a big part of the story.

The idea so intrigued me I had to rush over here and ask for some suggestions of stories that handled it differently. I would be pathetically grateful if a few recs could be tossed my way, of stories in which John's father or mother were revealed to be an ancient.

P.S. Not necessarily a requirement per say but I prefer McShep stories
