I thought I recall there being a few Ragland relatives who seemed very fond of Meghan and said lovely things about her when interviewed.
Yes, some relatives were tracked down, but they admitted that they never met Doria or Meghan. They liked what they saw on TV etc. regarding them and wished them well, but that was it. They never met them.
From what I have seen online, I think there was mention of Doria's aunt and a distant cousin who is a young graphic designer from NY. Both were said to have been at the wedding, but tbh, I did not follow this up much, so I cannot verify. It was reported that they both knew Doria, but not Meghan that much. You have to have doubts of course, considering that it's said they don't talk to the media.
