No, she is Grandparents came from Russia to flee pogroms Jewish. It was me she was concerned about. The Rabbi called Mrs. Plant (v.2.0) and said she was welcome.
Ah I misread your post. Of course, if your wife was Jewish, your being a Conservative convert should not have had any impact on your wife’s visiting a mikvah.
She took me to Brookline to buy a tallit, and we got ugly looks from the lady in the store.
I guess I don’t look Jewish. 
The ridiculous part of that whole deal is that Conservative Judaism hasn’t even been around that long. So unless your rabbi’s wife was a convert to Judaism rather than descended from Jews, chances are pretty low that someone in her ancestry wasn’t Jewish according to Orthodox standards. (Same as the case with my family AFAIK, which is going back ~ 4 - 5 generations to various locations in the former East Bloc, and it wasn’t too long before then when written family records become spotty at best, either because they never existed, or because they were destroyed in WWII. Not to mention before Jews had last names in the Western sense, which makes genealogical research pretty damn difficult.)
Just for kicks, here’s but one story of the problems people run into documenting their Jewishness to get married in Israel.
I’ve heard both of those jokes applied to Christians, too: “Saint Michael And All Angels was the church he avoided going to, and he wouldn’t dream of avoiding going to another.” And the desert island people are Baptists.
