I'll drop in my two cents, although my family's spirituality is more "American" than "European."
My family is about as diverse as you can get. My father is a mix of a bunch of nationalities and my mother is as well. In fact, my mother's mother was Tsalagi and grew up speaking their language at home, a fact I didn't learn until long after her death. (I always wondered why she and her siblings always spoke with funny accents and did things I thought were abnormal. I also knew my Uncle Sam went to the "Cherokee Baptist Church" in Tahlequah and not to the "normal" church. I didn't realize their services weren't in English. I will cease my digression.)
I have two families: my spiritual and my physical.
I have found that I can grow by practicing the faith of my spiritual family and ancestors. I learn from these saints and from the traditions of the Ruthenian people. I don't consider them any more foreign than my grandmother saw English Protestantism. Ethnically I'm not Ruthenian and I don't need to be. In practice I have adopted some Ruthenian traditions as they affect religious holidays. I don't suppose that is any stranger than Ruthenians taking up Greek Christianity.
For my physical family, I still respect many of the few traditions I received from my parents, and my wife, who is half Polish and half Slovak, has added her traditions to mine. Our son will receive the benefits of the many cultures from which he has come, including those from the struggles of the people that brought us our Byzantine Catholic faith.
So my little family has its own identity; one which is "ethnically" and "culturally" unique, and thoroughly Eastern Catholic.
As for the veneration of saints, if the church recognizes them and I have the desire to venerate a saint, I don't worry about their ethnicity as long as they don't worry about mine.
To be honest, I don't know how some of you "single" ethnic background folks do it. I guess people are like Scotch: single malts get all the attention, but some of the blended stuff is pretty darn good.
