Do you have a listing of William's siblings?

I am still looking for information on my Gr Gr Grandmother

Mary Jane Shaw ( aka Jane Shaw) - Scotland
She married William Henegan - Co. Sligo, Ireland

My Great Grandfather was their son John Henegan.

The family immigrated 1849-1850 to the USA.
Came through New Orleans and migrated to Ohio.
Census records show them in Cincinnatti Ohio in 1850
at some point they migrated north to Knox County, settling in Mt Vernon.

John married Mary Barry who was born in Ireland.

Among their children was a set of twins.
Catherine and Isabelle born March 8, 1863

Isabelle is my grandmother. Not Great Grandmother but Grandmother.
I was born in 1954.

Isabelle married Patrick Finneran and one of their sons Barry D Finneran was my father.

I am searching for Jane Shaw's burial place.
I found William's in Keokuk Iowa but Jane is not buried there.

In 1880 Jane Shaw was living with my Gr Grandmother Mary Barry Henegan in Mt Vernon, Ohio.
I cannot find anything else on her.

Any help will be appreciated. Thank you

Michele Finneran Williams
