There is an elder in a congregation close by whose wife, a pioneer, told me that they attended a wedding in a church of one of her family members. She had told her husband that since they never went to the holiday things her family had, she was afraid her family would think that she and her husband did not care about them at all if they did not attend the wedding. There were no repercussions over it, but I am not sure who all knew.
My experience has not been the elders saying anything about it, but people within the congregation, usually less educated and more ignorant ones. I learned to not tell anyone anything about my life, and I really did not socialize with the people in the congregation. My husband and children were not witnesses and we had our own life.
