Gram/Parelius

I have been updating my records and have found differing entries on slekt.net and hemneslekt.net. Could anyone help me sort this out. One entry states Ellen Gram - married to Niels Rosing Parelius children - Rasmus Parelius b. 1842 - Jakob Schaweland Gram Parelius - Maren Anna Chatarina Parelius Father - Jacob Schavland Gram Mother - Ingeborg Henrikka Tokset The other entry states Ellen Gram - married to Niels Rosing Parelius children - Johanne Elisabeth Gram Parelius - Jacob Scharland Gram Parelius (name different) - Maren Anna Gram Parelius - Maren Anna Cathrine Gram Parelius Father - Marcus Schavland Gram (name different) Mother - Ingebord Henriccha (different spelling) As Johanne Elisabeth from second entry was born in the same year as Rasmus Parelius from first entry it seems one of them must be incorrect or one of the dates of birth is maybe incorrect. Why are all the children not mentioned in both lists Thank you Carol[:)]
