AITA for continuing with my wedding despite a family bereavement?

I celebrated my marriage to my new husband last weekend. We got legally married abroad (in the country where we reside), and returned back to the country where both my husband and I were born to celebrate with family and friends, in a traditional wedding setting. All family still live in the country; some friends were travelling especially for the celebration.

Very sadly, on the day before the wedding, we were told that my uncle's wife had passed away overnight. She passed of natural causes, aged 77. We were of course very sad to hear this, and sent condolences to both my uncle, and my cousins.

We did not choose to change anything regarding the wedding. We had invited my uncle, his wife, and all of my cousins and their families, and understood entirely that they were grieving and likely not to attend. To note, my uncle's wife was not biologically related to any of the cousins, having married my uncle around 10 years ago, though she was of course a grandmother figure to my cousins' younger children. Some of the uncle's children, and their families, did still choose to attend (they said that their uncle had said to pass on his good wishes, and thanked us for thinking of him during this time). During the reception, we asked our guests to join us in a silence to remember those we had lost, especially my uncle's wife as it was so recent.

After we shared some photos online a few days ago, we started to get comments saying that we were selfish and conceited for continuing with the wedding despite there being a death in the family. We didn't recognise any names of the commenters initially, but found out that they were relatives of the uncle's wife. We were not going to respond, but unfortunately the comments were so frequent and harsh (there were some very firm comments suggesting that we had brought shame on both our families, and that we should not be allowed back into our country) that we ended up deleting the photos.

I know there are people grieving, and of course respect that these people feel like their family member's passing has been ignored. At the same time, I feel like we cannot help that our wedding was planned for this time either. I do not know any of the family personally to reach out to them, and do not want to burden my uncle with this when he is managing the loss of his wife. I have considered a public apology, but do not know if this is overkill.
