I came out to my parents and brothers and sisters the other week with rather mixed results. I came via letter/email using a letter based on the sample letter in this forum and didn't do enough to make it personal, which hasn't gone down well.
Despite that my mother has taken it better than expected, her main concern was that she had just never had the slightest idea that i was trans - which may show that i hid it really well, or that she just never saw the signs. My brothers have been ok, and my brothers daughters were wonderfully supportive, while my sister and her husband are really struggling.
At least everybody kows now, so no more secrets; now just waiting to come out fully at work.
