Kaodi
Legend
I think the minor connection would be fine. Teea has a mishap while experimenting with dragonpowder and Shendra arrives on the scene and tends her wounds. The fact that Teea is a bit younger could trigger Shendra's instincts to look after her (even though her own daughter would still be in the six to eight range).
With Mei Ying I am thinking that the connection could rely on a generous reading of Shendra's Whispered Glimpses ability: the arcanist is interested in the Thassilonians and the Runelords and as such Shendra received some particularly strong intuitions about her and her interests. Shendra then used her tremendous people skills to make a favourable impression on Mei and they struck up a casual friendship. For Mei's part perhaps she has a feeling there is something she ought to recognize about Shendra as well, whether it is her Azlanti appearance, much stronger than the echoes seen in native Varisians and Shoanti, or her actual resemblance to a Runelord.
