I’ve done a bit of research and Stuart-4 seems to be her father

Crofts-68 and Walter-2 appear to represent the same person because: They are both profiles of Mary, an illegitimate daughter of Lucy Walter. Lucy was a mistress of Charles II and was the mother of his illegitimate son, James, Duke of Monmouth. Mary was also an illegitimate daughter of Lucy Walter but her father is uncertain. Some have suggested that the father was also Charles II, but others indicate that this is not possible.

Mary is therefore the half brother of James Duke of Monmouth.

Mary married firstly William Sarsfield esq. and secondly William Fanshawe. As you can see. Crofts-68 was married to Sarsfield and Walter-2 was married to Fanshawe.

My suggestion is that Crofts-68 is merged into Walter-2. Why so? We know that her mother was Lucy Walter but her father is uncertain.

NB The link with the surname Crofts name comes from her half-brother, James Duke of Monmouth. He took on the name of Crofts from the people he was brought up by. However, Mary has no link with Crofts as far as I am aware.

Crofts-68 and Walter-2 do not represent the same person because: Different LNAB, born in different countries.

Crofts-68 and Walter-2 appear to represent the same person because: Same dates. It is difficult to determine which surname at birth to use. She was the illegitimate daughter of Lucy Walter, hence Walter may be the appropriate surname. Her brother/half brother took on the name Crofts from a family he was living with as he grew up.
