August - Just a windy month?

There's an old urban legends which says that August takes some lives away. I've always laughed at this, but this year the legend is being frighteningly near some relatives.
Last week was a different week. On Sunday I realized that my son had chickenpox. I was quite worried, sad and desperate because I'm not accustomed to have my son sick. He is a healthy boy who only got minimum flues and some coughing from time to time. So, having him with blisters all over his body, and even worst, in his throat, it was pretty unbearable for me. I didn't know what to do to help him feel better, he wouldn't eat anything because of the pain, but he was hungry anyway. I was helpless. I bought him some yogurt, and part of the problem was solved.
By Thursday, my husband's mother called him to say that a healthy relative had just passed away. We stayed puzzled. The woman who died, was not one of my favourite relatives from my husband's side, but she was a person, a healthy person. Why should she die? And more important, why should she die out of the blue? Without notice, without being sick, out of the blue. She started feeling a strong stomachache a week before, and the doctor advised her to have some medicines. She took the medicines and started a healthy diet. At 4 a.m. on Thursday, she told her husband that she was suffering a splitting headache, and by the time her husband went to look for the car keys to take her to the hospital, she lost consciousness.
The weird thing is that the whole family was expecting the husband to pass away, because of his diabetes and the problems he has had for not being careful enough with his health.
Anyway, by Friday, my husband went on a minor surgery from one of his toes. So, instead of having one Leo male sick, I had TWO. Leo males are quite demanding when they are sick. They tend to be extremely attached to their mothers, which meant that I had my husband's mother more often than I wished. What's worse, I had my husband's mother 'suggesting' ways of treatment for her son and her grandson. My God! I thank everyday for the patience I have. If not, I would have sent her to hell and I would probably have had many quarrels with my husband.
Of course, I didn't go to school on Friday, but one of my friends sent me a message asking about my family's health and told me about one of her friends' father who had died that day.
For this series of unfortunate events, I started wondering about the urban legend that I've always heard from old women about this strange characteristic of August. Is it true, or just a weird coincidence? As i said, I've always laughed at this and every urban legend, but this year I decided to doubt, and not be one hundred percent certain of the non-existance of such possibility.
