That's an interesting page. Most of the decedents are dated 2005, and nearly as many are 2004. There is only one in 2002 and one in 2000, then one in 1964, but Sister Lucia (# 265) is the oldest death, Def: 31/05/1949. If so, then she actually died May 31st, 1949 -- unless somehow that's a mistake.
.
Why would they have her listed among so many others who died in 2005?
.

Well, the official date they give for her death is 2005.  So that's why she's in the list but someone slipped up and, looking in some other record, accidentally put down the real date?

.
If the real date was posted by mistake in her case, perhaps the real date for other sisters was posted by mistake in their case(s) too.
.
This old list of vital statistics could be compared to a new list, to see whether any of the dates for the other sisters are different. But where do you find the new list?
.
There are a number of oddities about this old list. They have two sisters dying on the same day in two places (total of 4 nuns, 2 dates) and there are two times when several died in the same week: the last week of November, 2004 shows three sisters dying (#241, #242, #243); two sisters died on December 5th, 2004 (#244, #245).  From Dec. 19th, 2004 through Jan. 12th, 2005 (4 weeks) they have 10 sisters dying, ages 88, 84, 77, 85, 91, 77, 98, 80, 67 and 81 -- the last 4 dying in the same week. Unless the population was in the thousands, this seems almost impossible. The next group of 8 deaths is shown between Jan. 16th, 2005 and Feb. 4th, 2005 -- they have a total of 25 sisters dying all within 14 weeks (#240 - #264). THEN, 9 days later following that last one (Feb. 4th) is when they claim Sister Lucy died, Feb. 13th, 2005.
.
The 6 deaths following Sister Lucy all happened within 3 weeks.
.
Overall, this one page depicts a tremendous increase in frequency of deaths. The first 3 deaths are shown over a period of 3 years. Two years from the first death to the second, and one year from the second death to the third. The 5th death listed (#232) is entirely out of order, like Sister Lucy's is. Maria de San Jose (#232) is shown as dying in 1962 at age 26. Why is Maria de San Jose listed as number 232 if she had been dead for 42 years in 2004?
.
Overall, there were 4 deaths prior to Feb. 2004 (if you include #232 being out of place), then 40 more in the next year (Feb. 2004 to March 2005). That's a FORTY-FOLD INCREASE in one year (4 deaths over 4 years to 40 over one year). Why the sudden increase? Something isn't right. These deaths occurred in many different places all over the world, and Sister Lucy's is the only death in Coimbra, Portugal.
.

Were the sisters killed off because they knew too much.

Body doubles, murder, lies are not Catholic.  So many sins is destroying the Catholic Church.  

.
There isn't anything to tell us that the other sisters listed as dying had ever known Sister Lucy. Why would they want to kill off particular sisters that lived hundreds or thousands of miles away, even in other countries from where Sister Lucy lived? They are being described as having lived and died in various places all over the world (Europe - France, Switzerland, Belgium, Spain, Netherlands, Germany, Ireland, England - South and North America, Philippines, India), while Sister Lucia is the ONLY ONE listed as having died in Portugal, between 1949 and Feb. 2005. It's curious that the suspected "real death date" of Sister Lucy is at one extreme end of the list (the first death date listed) and the date when her double is suspected of dying is at the opposite end of the list.
.
Several of these sisters were born in the same small town where they would later die, and others were born and died within a small area of one country. One sister (#258, born in London, died in Quidenham, Great Britain at age 92) has the name "Joyce" and birth name "Parker Joyce." Apparently that means Joyce Parker. But in my experience all sisters take a new name when they take final vows. Joyce is not a new name. Perhaps this is another typo. So it could be a list rather unreliable in its details.
.
All in all, there must be something missing. This one page is not enough information to go by. But it seems to be enough to raise suspicions.
.
I don't see anything there that alludes to evidence of anyone being murdered because they knew too much.
But at the same time, neither is there shown anything indicating that no one was murdered because they knew too much.
