Do not know much about Jane Mussen. She was married to Henry Switzer Van Fleet, and had two children. The first of which was Henry Munsen Van Fleet, who later moved to Texas, and the second was Lucy Jane Van Fleet, then Lucy Jane Maguire, Shortly after her birth, Jane Mussen seems to disappear from the radar. She may have passed during child birth. Henry Van Fleet by 1860 is married to Esther Flandreau and has 8 children with her over the upcoming decades. Lucy, their daughter is shown to be living with Henry and Esther Van Fleet in the 1860 census. How Henry Munsen Van Fleet got to Texas is a bit of a mystery, or where he was from the 1850-1870 period time frame.

I had up to recently thought she may have passed at the birth of Lucy Jane, however, there are some things that lead me to believe she lived past that. She may have died in New York in 1863, as I have seen some records of that but those are not verified.

Here is a poem written by Jane Van Fleet in 1849.
New York
1849 Nov 29

Presented to Miss Margaret Mussen by her friend Mrs. Jane VanFleet

When the Moon on the Lake is Beaming

When the moon on the lake is beaming,
And the night is calm and still,
And the stars in their bright lights gleaming,
Shine forth on some distant hill.
Shine forth on some distant hill.
Oh! Come – love come – oh come with me!
And I’ll give thee a happy home,
Where a true heart waits for thee.
When the moon on the lake is beaming,
And the night is calm and still,
And the stars in their bright light gleaming,
Oh come! oh come – love come – oh come! love come
When the vesper bells are singing,
Their ev’ning melody;
Or maidens sweet are singing,
Their simple minstrelsy,
Their simple minstrelsy.
Wilt thou come? Love come! Oh come with me –
And I’ll give thee a happy home,
Where a true heart waits for thee.
When the moon on the lake is beaming,
And the night is calm and still,
And the stars in the bright light gleaming,
Oh come! Oh come – love come, Come love come.
