I am unable to locate any primary sources that support the existence of a daughter Margaret born in 1859. The fact that Ada (Cochran) Ritchie (1858-1902) was born the year before and Walter W Cochran (1860-) the following year also makes it quite doubtful.
If you are able to find reliable sources that confirm her existence then they would be great to add. Otherwise, I am inclined to suggest that the profile is superfluous.
