This was a tough one! Did your FRANK ALBERT LAROSE marry MARY E GRACE? If so, you're in luck. In the "Vermont Marriage Records" on Ancestry.com is the actual image of their marriage record - it is transcribed below:
GROOM: FRANK A LAROSE
BRIDE: MARY E GRACE
DATE OF MARRIAGE: APRIL 26, 1923 in Starksboro, Addison, Vermont
PLACE OF BIRTH OF GROOM: Ferrisburg, Vermont
GROOM'S FATHER'S NAME: FRANK ALBERT LAROSE
GROOM'S FATHER'S BIRTHPLACE: FERRISBURG
GROOM'S MOTHER'S NAME: SUSSIE LAROW
GROOM'S MOTHER'S BIRTHPLACE: FERRISBURG
Also, on the Death Record of your FRANK ALBERT LAROSE, born 1899, died 1968 - it states the name of his father is ALBERT LAROSE.
I found SUSAN LAROSE on the 1900 Ferrisburg, Addison Co., Vermont Census - transcribed below:
Head of household, SUSAN L LAROSE, age 27, born Jan 1873 in Vermont, widowed, parents born in Vermont, she rents her home, occupation is "laundry work".
Son, EARL L PALMER, age 6, born May 1894 in Vermont.
Daughter, RUTHIE M LAROSE, age 2, born Mar 1898 in Vermont.
Son, FRANK LAROSE, age 5 months, born Dec 1899 in Vermont.
The Census taker was to ennumerate each individual that lived in the household as of June 1, 1900 - so I knew that FRANK had died before that date.
I found a LAROSE FAMILY tree on ANCESTRY.COM - the owner of this tree is "tplwesco", that lives in Florida. If you subscribe to ANCESTRY, you can find this tree and contact him.
On his tree he lists a FRANK LAROSE, born June 9, 1872, died April 4, 1900 in Ferrisburg. I believe this to be your FRANK LAROSE, married to SUSAN. He even has a copy of the Death Record of this FRANK LAROSE - transcribed below:
FRANK LAROSE - Died April 4, 1900 in Ferrisburgh, Vermont at the age of 37 years 10 months; he was married; his occupation is "farmer"; he was born in Hinesburgh (? hard to read); his father is WILLIAM LAROSE; his mother is MARGET; the disease causing death was typhoid fever for a duration of 2 (?hard to read) weeks.; ______ attendent E O REYNOLDS; Town Ferrisburg, Vermont.
I emailed myself a copy of this document so that I could email it to you, so please contact me.
This person states that FRANK LAROSE'S father is WILLIAM L LAROSE, his mother is MAGARET AMELIA BROUGHTON. There is alot of information on this family tree that I'm certain you would like to see.
Hope this helps you. I know that you stated his name was FRANK STEVENS LAROSE, but I believe, from the documentation, that it was FRANK ALBERT LAROSE. Sincerely, Melinda
